Discipline Icons for Guitar/Piano/Ukelele/Bass/Singing
Make icons next to the song titles in the song lists, that represent if a guitar/piano/ukulele/bass/singing version also exists for that song. So if you cross train piano and vocals or ukulele and vocals
etc., youu know which songs have a counterpart in the other discipline.
be able to filter by songs that are available to an instrument other than your own to find songs that can be played together
This is a great idea. It's my idea, but I'm just saying, it would be awesome!
