Automatic Staff Space Option
I really like the new feature in MuseScore 3. The staff distance automatically adjusts to dynamics, articulation markings, etc. However, I think that there also needs to be some sort of automatic staff space option for the Page Settings. I don't like how some staves get too big that some pages only have 3 sets of staves when there are supposed to be 4. I'm not sure if I described it properly, but I hope you understand what I'm trying to say.
Maybe in the Page Settings, there could be some sort of option where MuseScore automatically adjusts the staff space depending on how many sets of staves you want per page.
