DickyDutch One little thing I’ve found so far is that if the “show lyrics on playback add” is selected in Settings and the red arrow button is pressed to load a playlist into the queue, the left hand side of the subsequent screen shows the list of playlists and not the list of songs.
I see where you are getting at, but this option works only with advanced queue mode activated. But why would you want to open the playlist contents? In my opinion it would make much more sense to switch to the queue tab so that you can manipulate the queue. I guess that would always make sense. If you replace the queue with a playlist, then switching to the queue tab seems like a good idea.
Regarding capo: I agree, for guitar players capo makes more sense, but I don't target guitar players exclusively and everyone else is much more familiar with transposition by semitones. And for a guitar player it is trivial to know which transposition corresponds to which capo position.
