Two things.

It seems that even though I have the part markers box unchecked that sometimes when I copy and paste while editing the part markers get moved anyway and my whole chord sheet gets screwed up. I think it happens after saving the song - I'd rather the default be unchecked.

Also sometimes I just want to delete a chord symbol from a bar (as in some cases this makes the generated track play differently)and I wish this could be accomplished as simply in RB as it is to do it in BIAB.
