Correct - I don't believe that was in the ChordPro documentation when I was first setting up the chord grid code. So it's another thing I'll have to account for.

Yes, ChordPro is evolving too.

Directives will gradually start accepting properties next to / instead of fixed parameter strings since the latter are too limited.

To maintain compatibility, ChordPro looks for the presence of the pattern \w+=['"] in the params. E.g.

{start_of_verse This is verse 1}             ← parameter string
{start_of_verse label="This is verse 1"}        ← property

itsme just encountered a case where the naive detection fails.
