OK, I know this is a petty request, but I have a mouse which has a click lock on one of my computers, and I've come to realize how useful this can be when using the straighten and rotate options of the tweak tool. I've also come to realize how old it can get when doing a lot of rotations and straightens to have to sit there and hold the mouse button down because I'm not always using the computer with a click-lock mouse.

I would like to suggest modifying those two aspects of the tool such that double clicking either the rotation arrow, or the straighten ball will act as if you had a click-lock. So that the rotation or straighten would continue indefinitely until you clicked again.
