Re: buttons for Hide Layer and a smoother zooming experience-- nope. I heard back and the answer is no good on that one. So that's that. For zoom though, there is Ctrl + = and Ctrl + -.... I'm not sure if that's what you're already using. Re: Rbutton changed to LButton on Line 135. I don't really understand why it matters, but yes, it solved the problem.... sorta. If I change it as you suggested, the Hover Zoom button now works perfectly for Resizing, just like the Drop/Color Picker tool does-- I push the button, apply pen tip to screen, and resize to my heart's content, with the sizing circle always visible. Lift it, and the I can go directly to drawing and painting again. Works wonderfully. HOWEVER, the Hover Zoom button no longer works as a zoom button very well after I change the code. Now, it sort of locks up after a second. Perhaps you were planning on breaking one function to figure out if you could make the other work? Not sure, but either way, that's the story so far. Of course, it would be nice to have both buttons work very well.... Will have to get to the timing of the repeat function on Undo tomorrow sometime. Pooped out for now!
