In the bar settings dialog it would be an improvement to have the chorus # selection remain as set rather than reverting to the default of 'all choruses' each subsequent time the dialog is opened.

Even better: Within the bar settings dialog provide an 'apply' button and a bar # selection button so that one may edit all bar setting changes in one session without opening and closing the window repeatedly.

Top of the wishlist: fix the various things that don't work right in the chord entry window (e.g. single-line scrolling).
