1. Assignable shortcuts.
2. I like the idea about the colors. how about this. hold right mouse button and scroll to swap colors. enable/disable that feature by clicking middle mouse button, and if disabled, returns to the 2 color mode. The buttons should also be assignable though.
Middle button could also open up the color picker, if you choose that.
The ability to customize the controls and shortcuts is important for any tool
