I’d like to be able to add text in the chord symbol lines.
One that I use in lead sheets is “Unison” to indicate that rhythm instruments play a written melody line (e.g. the end of each chorus in “Isn’t She Lovely”.)
Now that we have multiple lines for alternative chords, it would be great to be able to add information like “2nd time” or “solo time only”. Possibly they could be prefixes to a chord symbol.
Of course, this can be done with system text, but it does involve adjustment in Engraving for each layout.
