When using the app to display chord charts on a gig (with the songs in a playlist listed on the left of the screen), it is very easy to accidentally swipe one of the songs in a playlist left or right, instead of selecting the song.
This is a bit of a nuisance on a gig, because you will be prompted to delete the file.

It would be nice if there were a way to "lock" a playlist so that it cannot be modified while on a gig.
This feature would ideally prevent you from editing any of the charts in the playlist as well.

Thanks,
