You can set the key in the song properties window (i.e. C major). Is there a way to display the key on the setlist/song view page (besides using a ChordPro file)? I’d just like it to display in the header section along with the metronome, tempo and time signature. If you have a big setlist, it’s hard to keep track of which key a particular song is in. This would be handy for live performance situations.
If this is not an option, I will add it as a feature request.
