Nice one, thank you for posting.
Feedback:
- why use a custom-text "m" symbol for "minor" when "m" is already in the chord picker?
- you didn't write the first "g" and "a" chords minor, but they look (and sound) like they should be
- be careful how you set the key. Take care to set it correctly in the "info" page, so you won't be confused if you transpose the chart using the automatic transposing function (he chart is in F, but you set the key in C...)
Cheers, and keep the music flowing.
