MUSIC SPACING when staff styles are applied
I very often use staff styles as an overlay over music that still plays back - actually the entire overlay idea is a smart move by Finale if you compare it to Sibelius.
In a typical situation, I would have a drum- or guitar-staff with rhythmic stuff going on, but there's a slash-notation staff style on top. Now, when it get's to music spacing, the notation underneath the style still somehow influences the spacing of the slashes - which I think it shouldn't.
So, (at least in the parts) the slashes should automatically use Time Signature Spacing - that's something I have to do manually all the time.
