It would be real nice to have a Search and Replace feature for chords. For example you have entered a song with many Gmaj7 chords and it turns out that a G69 is better. So instead of pasting G69 many times over, you could choose Edit and then choose Replace. Then you would enter what to replace, in this case replacing all Gmaj7 chords with G69 chords. The search and replace I'm referring to is like in many word processors like Microsoft Word or Wordperfect or even in like in spreadsheets like Excel. My intention is mostly for this feature to be in the Chord Sheet view, but there could be some options/parameters allowing it to work in the Notation views where notes could be changed -- for example replace all notes "G B D" to become "G A D". It could be done with or without a prompt. You could have all the changes done at once or the option to see the proposed places for the note or chord changes.
