An oddity I found…
In engrave mode (vs 1.1), note spacing on, I move a bar line to to get the 3 measure multi-bar rest a normal size.
It produces 2 system breaks (this confused me initially, but now I think I understand why).
When I go to delete the system break on the second line, it shoves all of the music into 1 line.
Pretty sure this is not by design. But thought I would bring this to someone’s attention.
