I was waiting for this. :)
It's a good idea, but the answer (for the config windows) is no.
Please keep reading for as to why. If I am not clear enough or you want
more info, please ask. :)
>However, putting too much layout info in mplayer's config would bloat
Worse, the layout info would be worthless for some toolkits / platforms.
I do not know of a way to represent it in a meaningful way for enough
They are too different.
For instance, writing a gui builder for GTK is much
easier than writing one for win32. Why? Because GTK uses containers/boxes
to hold controls.
In GTK, you just put controls in boxes and don't worry about the
because those are handled automatically. This is so nice, because
windows always tend to look good --even when they are resized.

There are a couple problems with this.
First, you would be doing the work twice, something I never like to do.
Second, if I understand A'rpi correctly, is that the whole system
is supposed to be dynamic. If I do my job correctly,
you guys should be able to add dozens of modules to mplayer and the users
will not have to upgrade the GUI. This isn't going to be possible
if xml tweaking is involved.
Third, the core gui builder code isn't that complex and
the config design is well thought out. This makes things much easier.
If I run into problems, we'll work things out.

That would be very hard to do and maintain. I am probably going to have
to write some algorithms for control placement (mainly how many controls on
page is too many), I will tweak those as necessary.
The most important thing is not jamming stuff together.

Yes, I believe you are correct about this (i.e more than just a flag).
I'm working on it. But, as I said earlier, I'm going to make sure it works
and the impact on the rest of the system is minimal.
