maemo.org - Talk - Screen Rotation

I'm not sure if this is the right place to ask the question, so I have no problems with this thread being moved if it needs to be.

I've recently starting using FBReader on my 770 and I really love rotating the screen in that program. Is there any way a program or a theme could be made so that more things could be rotated? Or is it up to the individual program developers? I don't think I'd always want it rotated, but I find its easier to use with one hand because my thumb can reach all the way across the screen when I rotate it. Just throwing the idea out there, I searched through the forums and didn't see anybody that had asked or discussed this yet.
