How many old leadsheets do you have with extra chords (hand)-written in above? Like a different key, corrections, additional alt chords, Nashville numbers?
That's what I need - extra lines of chords.
In the software you could just add the functionality of verses to the chords - verse 1, verse 2 etc.
I've tried just adding lines using lyrics tool, awkward, and the size adjustment is not great, but it can be done, and thus shouldn't be too hard to add to Finale.
