Feature request: Skin layout depending on file type

[ilomambo]

Music files need a different set of buttons than video files or DVDs.
Why not having the player choose a different skin layout for each type of file?

Audio does not need any subtitle button, or aspect ratio button,
it does need equilizer, preamp, for example.
Video uses much more jump buttons than next/previous
DVD probably needs chapter and title buttons, etc.

You get the idea. I realize this is not a minor change, but it is something
doable for some future version; and it is really useful for the users.

(By the way, the whole interface engine could use a revamp,
and the skin scheme needs a complete upgrade to make it
consistent within itself and more flexible)
