+GuiLua is basically a redo of my ancient Java based matrix-RAD system,
+but using Lua and EFL. Lua is entirely different from Java, and Lua
+doesn't run in web browsers, so this version has similar concepts, and
+similar names, it's not exactly the same. It's more accurate to say
+this is in the spirit of matrix-RAD.
+
+The ultimate goal is for the various ClientHamr parts to be able to
+either host their own UI, or have it hosted in the in world 3D window.
+Matrix-RAD's ability to run either server or client side, with no change
+to the code, is great for this sort of thing. If I can manage the
+ability to "tear off" windows, in other words, pull them out of the 3D
+window to be real windows, then that's something people have been asking
+for from LL forever.
+
+Stdin/out might be good to use. Extantz starts up "client" programs,
+with a "use stdin/out" argument, the clients pass skang commands (open
+this internal window with these widgets) to extantz through their
+stdout, extantz passes skang commands (these values where set by these
+widgets) back through their stdin. With no "use stdin/out" argument,
+the programs host their own UI. Perhaps extantz can just pass the UI
+skang stuff back to the client, which will mean "draw your own window",
+to support the "tear off" feature. If I remember skang had suitable
+serialization stuff to support this. Lua does anyway. B-)
+
+Naturally, like matrix-RAD, all this UI stuff can happen across a socket
+as well as through stdin/out. Should be transparent to the user proggy.
+
+I can redesign skang to be more Lua like, to take advantage of Lua's
+meta language capabilities. Since no one used skang anyway, I can get
+away with this. Also should add a Lua friendly wrapper around nails, so
+that addons for Extantz can be supplied entirely as Lua scripts. In
+other words, LuaSL scripts. On top of all that, should also allow
+access to the Edje Lua stuff I've already written, but drag it outside
+of an edje file.
+
+This pretty much means that GuiLua should be a shared library, coz in
+the ClientHamr use case, several programs are gonna be using it at once.
+Should also be separate modules for development stuff like the skin
+editor, which could be just another proggy using GuiLua.
+
+Initially GuiLua can wrap elementary / evas, with the goal of wrapping
+NAWS, just like matrix-RAD was originally planned. Then I can put off
+writing NAWS for another decade. lol
+
+Might be nice to have a wrapper that is a web server that generates
+standard HTML forms. No JavaScript, no HTML5, just plain old,
+compatible with everything, HTML forms.
+
+
+Design notes
+------------
+
+Edje Lua does not wrap elementary widgets, and is not likely to due to
+elementary being compiled after edje. Smart objects and swallows
+probably can deal with that though, I'm not familiar enough with them to
+know. Eo on the other hand allegedly offers introspection, which was
+always the corner stone of matrix-RAD. So access to elementary widgets
+via Eo might be possible. That's kinda the entire hook I'm hoping will
+help to make matrix-RAD style stuff work as well as it did there.
+Apparently when they promised introspection with Eo, they meant compile
+time, not run time.
+
+Edje Lua is restricted to scripts in edje files, AND sandboxed to those
+edje files as well. We want to step outside that sandbox, and run stand
+alone Lua scripts, as well as GuiLua / LuaSL scripts internal to
+extantz. Some merging of LuaSL and Edje Lua, leaving room for GuiLua,
+would be great, but I might have to convince Raster. Note that the
+socket idea wont work in sandboxed edje Lua scripts, unless the socket
+is in C code, that uses edje messages as the internal transport.
+
+Just so it's easier to find, I'll repeat a bit from the Enlightenment
+mailing list here, the result of discussions with raster and other
+interested parties -
+
+"First step is to write edje functions for generically bundling up one
+or more Lua tables into a message, sending that message, then unpacking
+it again. This will be able to be done from edje, from C, and from Lua
+directly. Perhaps adding that as one more edje messege type. This is
+for sending Lua tables between threads. A later addition will be to
+send them through the 'net, probably as eet.
+
+Host apps can register arbitrary functions with edje Lua, using a more
+generic version of the code I already wrote for letting edje register
+lua functions. These host functions are by default not thread safe.
+Edje puts a wrapper function around the host app, and registers that
+wrapper function with Lua. The wrapper function, when called from Lua,
+does this -
+
+ecore_thread_main_loop_begin();
+call the host app callback();
+ecore_thread_main_loop_end();
+
+The first alternative, which the host app must request, is for the
+wrapper function to use the table message functions to marshal the
+arguments, send it to the main thread, wait for the response (or do
+something else), then unmarshal the result before sending it back to
+Lua.
+
+The second alternative, which the host app must REALLY request, is for
+the host app to say "I'm REALLY going out of my way to be threadsafe,
+just call me direct". No edje wrapper function, BUT the host app still
+has to use edje to register this function.
+
+The first two might be done this way -
+
+host_cb = edje_lua2_functions_add(...);
+edje_lua2_function_marshal_set(host_cb, function);
+
+The last one could be -
+
+host_cb = edje_lua2_threadsafe_function_add(...);
+
+Note the difference between _functions_ and _function_. The first call
+registers an entire metatable full of functions, in the same way that
+edje does for it's functions. These are the default sort of
+functions. The second call references one of those previously
+registered functions, and makes it marshal arguments and results. The
+third one registers a single function, but it could be added to an
+existing metatable registered by the first function."
+
+and -
+
+"We are actually half way there. Anticipating that there would be way
+more edje and evas stuff to add to the edje Lua API in the future, I
+created generic wrapper functions to make that easier. Implementing
+this would mean exposing those static functions, and writing more of
+these generic wrapper stuff.
+
+Lua already provides a mechanism for this sort of thing, but we
+currently sandbox that out. We can provide a very limited version of
+the package module, that only lets the Lua script load modules that the
+host app explicitly provides. This keeps edje Lua in it's strictly
+sandboxed state."
+
+Raster also wants to thread lots of edje, likely including having edje
+Lua scripts as threads, much like I'm doing with LuaSL already. Plus
+LuaJIT SPEEEEED!!. B-)
+
+
+Skang notes
+-----------
+
+So, what will this variation of skang look like? For a start, the
+syntax will have to be more Lua like, so that's a real basic change.
+Can't use a space as an argument separator, Lua allows only ',' and
+';'. Strings can still use single or double quotes.
+
+The magic "_123" system I used before to specify "position / size in
+characters instead of pixels" just wont work in Lua. Using _ as a table
+name with a meta table means that this syntax now becomes "_.123", which
+is kinda acceptable. Note that _.123 is syntax sugar for _["123"], so
+I'm not sure if using a number there works. An alternative is to just
+use a string -
+
+foo = widget.label(0, "1", 100, 0, 'Text goes here")
+
+Uses as many characters, and ends up being a value instead of an index,
+which is the right thing to do. While on this subject, anything less
+than 1, but more than 0, can be used as a percentage, maybe combined
+with "character" mode (this is a new thing) -
+
+foo = widget.label(0, "0.1", 0.5, 0, 'Text goes here")
+
+This could even allow relative placement as mentioned in the skang TODO -
+
+foo = widget.label(0, "otherWidget+0.1", 0.5, 0, 'Text goes here")
+
+
+"widget" would be a table with functions for dealing with widgets. It
+would include metatable stuff for widget set introspection. So
+"widget.label" would introspect in our widget set for a widget type of
+"label", and return a widget type table. So we could do -
+
+foo = widget.label(0, "0.1", 0.5, 0, 'Text goes here :")
+foo:colour(255, 255, 255, 0, 0, 100, 255, 0)
+foo:hide()
+foo:action("skang.load(some/skang/file.skang)")
+
+Also allow access via table elements -
+
+foo.action = "skang.load('some/skang/file.skang')"
+foo.colour.r = 123
+foo.look('some/edje/file/somewhere.edj')
+foo.help = 'This is a widget for labelling some foo.'
+
+We can use the concat operator (..) to append things to widgets, like
+adding choices in a drop down, rows in a grid, etc.
+
+Hmm, need a skang table as well -
+
+skang.module(Evas)
+skang.module(Elementary)
+skang.clear()
+skang.load('some/skang/file.skang')
+
+
+I don't think we need variable introspection as much, since in this case
+Lua is both the skang and the underlaying language, the variables can
+just be accessed directly. Not sure on this, need to experiment. This
+is what we normally need variable introspection for -
+
+foo = 'bar' -- Using the metatable to override '=' to set the actual value of the widget, say the text of a label or edit widget.
+bar = foo -- The reverse of the above. Though perhaps these can't be done?
+foo = foo .. 'stuff' .. 'more stuff' .. 'another line of the dropdown or whatever'
+
+OK, first two can't be done, metatable only overides that for table elements. The third one can only be (I might be wrong there) -
+
+foo.value = 'stuff' .. 'more stuff'
+foo.value = foo.value .. 'another line of the dropdown or whatever'
+
+Skang relied on the use of the set command to make sure that any
+matching widgets and variables got updated. And the get command.
+
+foo:set('stuff')
+bar = foo:get()
+
+On the other hand, given the module / package stuff mentioned below, and
+some metatable magic, we could do -
+
+local other = require('otherPackageName')
+other.foo = 'stuff'
+bar = other.foo
+
+Sooo, how does that squeeze into a "skang" file?
+
+#!skang myApp.skang -- This is Lua, so this might not work.
+-- There's an implied local this = require('myApp')
+-- There's an implied local skang = require('skang')
+local widget = require('EvasWidgets')
+local other = require('otherPackageName')
+skang.clear
+skang.window(200, 200, "G'day planet.")
+quitter = widget.button('Quit', 0.5, 0.5, 0.5, 0.5)
+quitter:action('quit') -- 'quit' is looked up in ThingSpcae.commands, and translated into the Lua 'skang.quit()'.
+other.foo = 'stuff'
+this.bar = other.foo
+
+
+Original Skang infrastructure
+-----------------------------
+
+Skang starts with a Thing as the base. In Java it's a base object for
+everything else, with a bunch of methods and elements. We can probably
+use a Thing metatable and replicate most of it. The widget used in the
+previous section is built on top of Thing. Things are stored in
+ThingSpace, which is a BonsaiTree of LeafLike Things. Java's version of
+multiple inheritance was used. Commands are a Thing.
+
+ThingSpace is per users session. classCache stores cached class
+lookukps, command stores commands, module stores loaded modules, param
+stores variables and their values, widget stores widgets and their value
+/ state.
+
+Skanglet is a generated mapping between actual methods / variables in a
+class, and skang. Each method or variable that ends up in the skanglet
+was marked by special javadoc tags. It also included some meta data
+like version and the default skang. For variables it defined -
+
+"Name", "Field/Method()", "Required", "Shortcut", "Default", "Help text"
+
+... and for methods -
+
+"Name", "Method", "Syntax", "Help text"
+
+In both cases the "Name" was the skang name, it could be different from
+the Java name specified in the second field. Likely we can do away with
+the need to generate these skanglet files, and just add stuff to the
+Thing. Modules wrap Skanglets, and takes care of loading them into ThingSpace.
+
+Module are used for -
+ loading the Skanglet for the Thing currently running (match java class name to skang file name).
+ loading the AWT interface in skang files.
+ loading OTHER skanglet based Things
+ loading Squeal, StuffSkang, and Who from java when needed.
+
+So in Lua, we can use the package system. First require(moduleName) to
+load up the skang module. Require can return a table, the Lua package
+called ends with "return someTable". See LuaLSL for an example. This
+package is actually run, so it can figure out what to put in the
+returned table. So for instance it could use inlined methods and such -
+
+local skang = require('skang')
+local result = {};
+result.author = 'onefang'
+result.version = '0.72 alpha 2004-11-19 16:28:00'
+local foo
+-- The first argument would be the name of a local variable / method. Which could be accessed via _G?
+-- Not sure if we could use a global foo, AND use it directly.
+result.foo = skang.newParam('foo', "Required", "Shortcut", "Default", "Help text")
+result.func = skang.newCommand('arg1_type,arg2_type', 'Help Text', function (arg1, arg2)
+...
+end)
+return result;
+
+
+Stuff is the base class used to track database rows and other multi
+value things. Would still need to deal with variable sub things, though
+that's likely just using tables. SquealStuff is the database version,
+using Squeal as the database driver wrapper. Squeal could wrap
+esskyuehl?
+
+
+The pre tokenized structure thingy I had planned in the TODO just wont
+work, as it uses symbols. On the other hand, we will be using Lua
+tables anyway. B-)
+
+
+NAWS
+----
+
+NAWS was always planned, but never actually written. Though some stuff
+was kinda prototyped, especially UberMatrix stuff. I think this time
+around, NAWS should be written in C, based on pure Evas + Edje. Perhaps
+with direct support for introspection? After EO settles down, I might
+use that to.
+
+
+Edje_Lua notes
+--------------
+
+Edje_Lua is sandboxed firmly inside of edje files. This makes it
+unsuitable for our use, as we want to step outside that sandbox.
+However, we still want to wrap Lua around EFL stuff, preferably using
+the same API. Raster fought against using this new eolian stuff to
+generate edje_lua2.c, and seems to be against having a "no sandbox" flag
+in edje_lua2.c. For now I'll let q66 go ahead with his Edje Lua via
+LuaJIT FFI conversion that uses a variation of eolian written in Lua.
+Seems like much more work than my way of doing it. shrugs
+
+Unfortunately, this might not be ready soon enough for me, AND it might
+not even be suitable. While I agree that LuaJIT FFI stuff might be a
+good idea, if I read the docs correctly FFI simply wraps around C
+headers and libraries directly, making it less suitable for sandboxes
+and other environments where you want to wrap those library functions
+differently.
+
+So, I might have to go ahead with my own plan anyway. On the other
+hand, for skang, I want to wrap things a bit differently. Might be best
+to do that wrapping C side. In other words, the skang and widget Lua
+packages get written in C, and are different from edje_lua2.c.
+
+On the gripping hand, there might be use in including edje_lua2.c style
+bindings in GuiLua as an edje package, evas package, elementary package,
+etc. This could be done by going ahead with my plans to modify
+edje_lua2.c to include the "no sandbox" flag, then compile it with that
+flag turned on to produce a standard Lua package. Then get eolian to
+produce evas_lua.c, elementary_lua.c, etc.
+
+Another idea worth investigating is to rewrite edje_lua2.c to use
+introspection directly to figure out it's "combined set and get" style
+bindings.
+
+
+Introspected EFL notes
+----------------------
+
+See below for the basic EO notes, where I come to the conclusion that
+the other EFL devs wont be adding introspection to EO themselves. It's
+all too hard they say. Pffft
+
+So, I might have to do this myself, call it "entro"....
+
+Write a patch against eolian that outputs introspection data. That data
+is C code for a hash of EO class names. Each hash points to a data
+structure that includes a hash of method names for that class, and a
+pointer to the class description. Each of those hashes points to a data
+structure that includes an array of argument types and names. The
+method ID should be in that structure to, and maybe even the doc text.
+Might even include an Eo internal data structure that links Op IDs to
+that method structure (I dunno what they call that). The final output
+is a library of that C code, that includes functions for doing the
+actual introspection.
+
+See? Not to hard at all, all described in a paragraph. lol
+
+One function we could include is a way to "compile" eo_do arguments.
+That would be an array (va_list actually) of method ID's followed by the
+arguments for that method. Some of those arguments might be pointers to
+memory structures, so this is not suitable for storing on disk.
+Instead, it could be used for "compiling" commonly used code or hot
+paths to get the introspection overhead out of the way early. Could
+also compile parameterized versions, with numbered place holders that
+get filled in later. Certainly we need a Lua interface to eo_do of some
+sort.
+
+In the same way that Java skang cached the results of introspection in
+ThingSpace.CLASS, we could use cache introspection lookups to speed
+things up. Not a great saving, one hash lookup versus two. Caching the
+"class.method" string that points to the method structure for any method
+we have used already.
+
+NAWS could use the compile function to create eo_do commands needed to
+create each of it's widget types, and the window. Yes, I know, NAWS
+only has two "widget types". B-)
+
+
+For quick and dirty early testing, I'll probably write a widget package
+that has hard coded mappings between some basic "label", "button", etc.
+and ordinary elementary widgets. Proper introspection can come later.
+
+
+LuaJIT FFI notes
+----------------
+
+LuaJIT 2.0 FFI needs to have cleaned up versions of C header files
+included in the Lua scripts that use it. This is messy. Version 2.1
+(or perhaps 3.0) has on it's road map to include a C pre processor,
+which should help that problem.
+
+
+EO notes
+--------
+
+tl;dr - eo introspection doesn't actually exist, even though it was
+"promised" years ago, but looks trivial to add. On the other hand, the
+other EFL devs seem to be fighting against it, so I might need to write
+my own. sigh
+

+ evas_line.eo.c -> EO_DEFINE_CLASS(evas_obj_line_class_get, &_evas_line_class_desc, EVAS_OBJ_CLASS, NULL);
+ Eo.h -> EO_DEFINE_CLASS is a macro that basically wraps eo_class_new(), and returns it's result.
+
+So Eo_Class is the type of a class, but it's A) opaque, B) deprecated!
+It includes a pointor to the Eo_Class_Description, which includes the
+actual name. I'm not seeing anywhere the names of the get/set
+paramaters being passed into the system, or any way to look up a class
+based on name. Not even a way to get to the public Eo_Class_Description
+from the opaque Eo_Class.
+
+Eo_Class_Description is at least public. It includes
+Eo_Op_Description's and Eo_Event_Description's. Eo_Op_ and Eo_Event_
+include the name and documentation of the op / event. The macro used to
+generate Eo_Op_ does NOT pass the name, just the ID number as a string.
+There is also Eo_Op_Func_Description, which does not include a name, it
+seems to be generated in the constructor. The same Eo_Op_ ID number is
+used to index it. Seems to be no direct link between Eo_Class and
+Eo_Op_func_, just the same Eo_Op_ ID numbers used internally somehow.

+EDJE
+Verbose, complex.
+Used to place and decorate widget parts.
+Can be used to place entire widgets through externals and swallows.
+Basic parts relative to each other.
+Signals and messages.
+Embryo scripts.
+Lua scripts (sandboxed).
+
+
+SKANG
+Tight, simple.
+Used to place widgets, and describe actions.
+Can include some really basic scripting.
+Widgets in a fixed position, but included stuff for relative placement in the TODO.
+Automated associations between widget name and variable (and method?) via introspection.
+Actions.
+Looks (could easily be extended to edje groups).
+Extensible.
+Can be used to pass values around.
+
+
+LL SHIT
+Verbose, even worse, XML, more crap than is needed.
+Menus.
+Windows with widgets relative to each other.
+ Basically nested rectangles.
+Manual association of widgets to methods.
+Can include tool tip string, enabled, visible, hover cursor, bounding rectangle?, mouse opaque?, tab groups, font (name, size, style, and alignment).
+ More stuff, typically hidden in the OO somewhere. sigh
+Generally uses fixed image and colour names, which skins overide.
+Skins can also overide the XML files.
+Translations provide override XML files that need only override the text bits.

+
+See if it's possible to disable the Emerald/Phoenix/Firestorm LSL bridge
+when connecting to OpenSim. Actually, they finally came to their senses
+and support OpenSim now, so that should be sorted already.

+
+Extant means "still existing, surviving", or the more archaic meaning,
+from it's original Latin roots "standing out, be visible, exist".
+
+Extent means "an area or volume, the range over which a thing extends"
+among other things.
+
+So I hope to invoke thoughts of a volume that exists and stands out. In
+other words, virtual worlds. Meh, I'm not that artsy, it needed a name.

+WoMan is a virtual world account and viewer manager, mostly of the SL
+(Second Life) variety since that's my focus. Most SL style virtual
+world viewers can be invoked with options to start them logging on, and
+skipping the login screen. So this project aims to be that login
+screen, doing all the things that can be done from the meta-impy login
+screen, plus more. Once the user hits the login button, woMan figures
+out what parameters to pass to what viewer, then starts it up and gets
+out of the way. Following the ClientHamr philosophy of breaking the
+viewer up into modules that do simpler tasks, and do them well. So that
+means that meta-impy will eventually loose it's login screen, to be
+replaced by woMan.
+
+WoMan starts off looking like any other viewers login screen, showing
+the login page of the default, or last visited grid, a small menu at the
+top with the usual functions, and the usual login buttons at the bottom.
+Added to that will be a better grid manager, with proper user
+management, suitable for people with more than one account per grid.
+The user will have the ability to choose a virtual world viewer to be
+the default, and even to associate a particular viewer with a particular
+grid. This is useful, for instance, for grids that have their own
+custom viewers, but the user wants to use a more generic viewer for all
+the other grids. Or if the user wants to use one viewer for OpenSim
+grids, but another for LL (Linden Labs) grids. Coz perhaps their chosen
+viewer is not TPVP (Third Party Viewer Policy, an LL thing) compliant,
+and LL are just more anal than the rest of the universe.
+
+NOTE: since I started this, LL in their *cough* infinite wisdom *cough*,
+decided that support of OpenSIm was a Really Bad Thing, so their viewers
+are no longer capable of dealing with other grids. LL have even gone as
+far as try to get other viewers to not support other grids. As far as
+woMan is concerned, this just means that LL viewers, and viewers that
+drank the LL koolaid, are less functional. shrugs
+
+The grid manager will also include some sort of search capability, as is
+currently being discussed by various people in the OpenSim universe.
+There might even be several search systems in place, so supporting
+existing ones, and the ability to add more might be useful. WoMan
+should be the only thing registered to handle hop:// and other such URLs
+in whatever web browsers you are using. Though most viewers want to
+register themselves, so tends to be that which ever one you started up
+last, or first, gets that privilege. That's a whole can of worms, sane
+policy and code should help.
+
+It might be useful to have woMan be able to download viewers,
+including checking for updates and offering to download them. As well
+as updates to common things like viewer tag definition files.
+
+WoMan, unlike the LL viewer code base, will be designed for relogging.
+Once the viewer it starts quits (or crashes), WoMan, which was still
+running, can pop again and let the user relog, or log to some other
+grid, or same grid as different a user, or even same grid as same user
+with a different viewer.
+
+Viewers can be made woMan aware, like meta-impy will be (since it's
+handing it's login screen functionality to woMan). A few more things
+make sense to be added in this case. For instance, you might want to
+have some or all of your LMs (LandMarks) be usable at the log in
+screen, so you can log directly to them. The user might want the choice
+when they HG (HyperGrid teleport) to actually start up a new viewer and
+just login to the other grid instead (if they already have an account
+there). While HGed to some new grid, the user might want to add that
+grid to the woMan grid manager at a simple click of a button, perhaps
+complete with an LM for their current position. The grid searching
+capabilities mentioned earlier might be needed while in world.
+Certainly the grid manager functions in meta-impy will be handled by
+woMan, even if in world.
+
+In order to display the login page of a grid, which is a web page, a web
+browser will be built into woMan. It could be used to display web
+pages within an woMan aware viewer. Though perhaps not for MOAP
+(Media On A Prim), unless woMan grows the ability to incorporate
+itself into the viewers 3D landscape as part of a prim. Which is a good
+idea, then meta-impy no longer needs a web browser. Though other things
+in the viewer are implemented as web pages, and LL are moving more stuff
+to the web.
+
+One of the things on the login screen is the menu option to start up the
+preferences window and change the viewers preferences. Viewers use XML
+files that not only store the preferences, but also a description of
+them. The preferences window and it's various parts are also stored as
+XML files. There is a bit missing that is in the viewer source code
+that ties all of this together. So it might not be possible to do this
+for all viewers. WoMan aware viewers can naturally provide the
+missing bits to woMan, even if not running, or even pass that entire
+functionality to woMan, just like meta-impy will do.
+
+For the purposes of keeping resource usage low, it should be possible
+for the user to configure woMan to go away when it starts a viewer.
+Might be a good idea even for woMan aware viewers, that can start it
+up again if it's functionality is needed while in world. Note this "go
+away" means to stop running and free up any resources it was using;
+which is different from the "gets out of the way" it usually does, still
+running, just not on screen.
+
+
+The problem with the web.
+-------------------------
+
+At least that's the theory. In practice, a web browser takes up almost
+one third of the viewer, and is only used for three things. Login
+pages, simple built in browser window, and MOAP (Media On A Prim). For
+the first two full blown web browsers are massive overkill. MOAP is not
+supported by meta-impy yet anyway.
+
+WebKit is a pain to compile at the moment, for reasons I wont go into
+right now. At the opposite of the spectrum is dillo, which is not quite
+up to spec enough for login pages that have fancy stuff. There does not
+appear to be any middle ground. So right now, I'll work on using random
+web browsers as external windows. That will suffice for everything but
+MOAP, which I can leave until later. Just discovered netsurf, a little
+smaller than dillo, but perhaps better featured? Might be useful.
+
+The web is a bloated mess, so it's not surprising that a fully featured
+web browser component like WebKit is also a bloated mess.
+
+
+Design.
+-------
+
+A thin window on the left.
+
+Menus across the top.
+View tabs.
+ Grids Accounts Viewers Landmarks
+
+Grids tab is the grid manager, though you can also drill down / tree out
+the accounts list per grid.
+
+Accounts shows accounts, though can drill down to grid list per account.
+Also consider launching thin viewers, text only ones and such. The
+account view is almost a natural for extending into a IM style thingy.
+
+Viewers lists the installed viewers, can install more, and allows
+preferences editing. It can handle viewer installs, upgrades, even
+compiling them from source.
+
+Landmarks manages LMs from viewers, or log in spots, or SLURLs etc.
+
+A user configurable web browser can open up to fill the right of the
+screen.
+
+Log file management features, including viewer stdout, check if only
+Linux viewers do that. Including chat logs.
+
+Dillo and uzbl can insert themselves into the windows of others. Should
+check that out. Netsurf is allegedly easy to port to things, might be
+able to port it to EFL.
