The volume bar thing is a known bug. Seems to be a timing issue that I can't quite narrow down. There are a few other ways I could approach a solution but I haven't investigated them yet because they're more work than I've had time for. But I'll definitely keep this in mind.

You'll have to give me an example of what you mean by "custom button controls." If you tell me exactly what it is you want to do with the buttons, I should be able to figure out if it's doable.

I tried doing the "squish" thing with the player screen early on in the development of 2.0, but because vfdlib (the empeg graphics library) doesn't have any image stretching routines, I had to use a 3rd party library, and it was very unstable for some reason. I might try again someday, though.
