It would be great if bar -1 could be renamed as bar 1, and bar 1 can be renamed as bar 3. That way we would still get the 2-measure lead-in and the bar numbers would match with a 3rd-party DAW. Right now I am having to add or subtrack two bar counts when swtiching back and forth from the events of Realband and my DAW. It's easy for one or two events, but when I have fifty different clips and tempo changes it becomes tedious.

In the Lead Sheet Options there is a parameter -> Bar # Offset, which is linked to an identical parameter in the Print Options. This parameter is missing from the standard Notation Window, though.
