Sure. But splitting up _one_ window into scalable areas is 
a somewhat different story.

While combining Blenders possibilities with traditional WM
features would be ideal, I don't see that happen.
Who would like to switch WM to use some special apps?
But a framework providing the described functionlaity inside 
windows on top of any WM could be a great thing (the WM managing 
windows and desktops/workspaces, the framework managing areas 
inside windows).

Oh, and WMs usualy don't manage loading/saving setups (Screens 
in Blender). And you can't change which app is displayed 
in a window ...

I think Blender's style is much more clear (where sections start/end). 
Also note that it provides no means to undock anything. A simplifying 
limitation, which has not shown to be a problem.
And the KDE and Gnome docking systems will be designed to work inside 
the scope of _one_ app.

Ion ... if I remember corectly it can't handle dialog windows gracefuly!?
However, it's certainly not for every one, and I'm disappointed, because 
this means your app has lots of little windows ...

In fact I'm working on the design of a general user interface around 
a document-centric, application-less system, where something like 
Blenders windowing system will be a part of.
The Y-window project might be a chance for implemenation of such ideas.
It's in any case my only hope for unified theming/widgets. Oh, and 
they plan to have widget as loadable modules, what should be great 
for the needs of audio developers (easy sharing, not reinventing the

As long as I don't have to run Ion ... ;-)

Hm, I'm more interested in combined audio/midi sequencers.
But I might look into it later on (no promise).

There are already so many WMs and themes ...
I found good enough themes/settings for my desktop. Since I will not be 
satisfied with anything less then an unfied desktop, I do not intend to 
put work into such things.
