Is there any way (short of reflashing to a totally new ROM) to add a "toggle auto-rotate" or "toggle portrait/landscape" option to the menu that comes up when you press and hold the power button?
I'm endlessly fighting with auto-rotation. For whatever reason, every Android device I've owned ends up being over-eager to rotate, but stubbornly resistant to rotating BACK, even when my gestures should be making it completely obvious that I didn't want it to rotate. However, every time I disable auto-rotation, I end up finding myself in a position where I have to rotate to landscape for something, and have to kill even more time trying to re-enable it.
For what it's worth, I have both a Galaxy S3 and a Xoom (wi-fi) (S3 running ICS, Xoom running JB).
