I often use Finale by opening two windows (I have two displays).
When I'm working on an orchestral project, with a huge amount of instruments, I define staff sets.
But, it seems not possible to use different staff sets on the two screens. I only get the same one on each.
It is strange, because I can choose between scroll and page views, but not between different staff sets in scroll view.
So, if I may suggest something to improve Finale, it would be to allow this option.
