After playing with it a little, a few suggestions: 1. Make it possible to (inertial) pan and pinch zoom when using a Mac trackpad. This would be significantly faster than using the lower navigator for Mac users. Also, I don't think it's a good idea to make the scroll wheel change the x-scale. 2. Add a shortcut for deleting notes when in "feather" mode — maybe middle-click? (I see right-click is reserved for changing layers.) This would make it possible to work on a piece of music without having to use the keyboard or move the mouse away from the canvas. 3. Is there a way to change the division of beats? IMO there should be a way to do this very quickly, so that I can switch between divisions of 4 and 3 for example. Great work! Out of curiosity, how long have you been working on this project?
