App: in library save chord progression and key#552

It would be awesome if when you save a song you could enter the key and chord progression In Nashville notation. Then when you fire the song the metronome as a guitar player it could show that static text and I could be reminded of the chords/song layout.

Would this maybe be solved by a generic “Song notes” field that could be displayed during the song and you could enter all kinds of text that would be helpful during practice? Because such a field is definitely in the works!

I have tried my luck at designing this today
