Quick note switch
Ok. Something that's always been a bit of an inconvenience is remembering which number goes with which note duration. So I got this idea (probably from a flash game, but I don't really remember.): what if there was a pair of buttons that were right next to each other that let us increment which note was being inputted, say, "[" and "]"? For example, let's say I pressed the number for a quarter note, but I really wanted an eighth note. So I press "[". If I want a half note, but pressed the quarter note button, I'd hit "]".
