This is related to a previous post, but allowing users to renumber bars (or at the very least, put in rehearsal marks that are numbers instead of just letters) would be great. I'm working on a big band tune that has lots of repeats. Any time I add a repeat BIAB throws off the bar numbering from what I'm following on my lead sheet and it makes it difficult to track down where additional repeats should go. Maybe there should be one numbering scheme for the program to follow and another user-labeled one.
