I enjoy the Alt+Right Click drag rotation feature because it snaps back to my tool after I've finished spinning. Same with the spacebar panning. Is there an equivalent key for zooming? The Z key is stuck in the magnification tool after I'm ready to paint again. Then I have to make ANOTHER laborious CLICK on the tool in order to get back to making marks.
I think a complain of this sort is a sign that you have a refined piece of software.
