Just as a bit of UX feedback, it's difficult to read this method of specifying the fingering. You display a finger-to-note lookup when you really want a note-to-finger lookup. It would be more useful to specify e.g. "left hand: 1 2 3 4 5 1 2 3" and "right hand: 1 2 3 1 2 3 4 5" for learning purposes.

Edit: most awesome would actually be an animation of the hand playing the scale with cross-unders and whatnot but that sounds like a lot of work.
