global chord format editing
S5 - Suggestion
The chord editor in the trunk is a good start. But it still wants you to edit each of the 100-200 chords separately. Better would be an editor that let you edit one canonical chord - say, C#ma7#11#5. The edits you made to the positioning of the elements in this chord could be propagated automatically to all other chords.
The new chord rendering system will make this largely moot - editing the XML file directly will provide this functionality - but still nice to keep in mind.
