I have not heard about ABC, yet. But I guess it would not really solve my use case. Converting from lead to chord sheets sounds nice, but playing piano with leadsheets, saxofon with Notes and guitar with chords (yes I'm using ChordPro already) require different notations and notes. So different files are somehow useful, but I would like to group the songs. So my list is not cluttered but only one entry of each song is listed. I imagine something like a folder. So the song is there, but icons/text indicate whether a chrod sheet, leadsheed or something else is present.
