One thing I've been wanting to develop is multiple levels to the alphabet list on the side (so you could tap the first letter, and then it would show a second list that is the second letters of all words starting with the first letter). This would allow the list to be used to jump to songs with much more precision, especially in the case of libraries with thousands of songs.  I could actually take this further and make it so that you, if you long press a letter, it pops up that second list, and if you long press any of those letters, it pops up another list and so on, until a letter is normally tapped. If # was long pressed, it would show first numbers.

I can see where this might be of use with numbered charts, but I think it would be quicker to use the existing search feature when looking for a title.  It never takes me very long to find an obscure title.  Thinking about it, I don't see why 'search' wouldn't work well with numbers?
