The capo setting is saved per session, but it would be much more useful to have the capo setting saved per song.

When playing multiple songs it is hugely unlikely that you will have the capo fixed in one place. If you use the capo a lot, this then makes the Jukebox feature very difficult to use. It would also be helpful to have each song display the capo setting prominently somewhere. Thus when each song loads it can be clearly seen where the capo is to be placed, without having to remember it for each song and having to scrabble around trying to determine where it should be.
