If you have staves that are hidden (because of optimization - I guess) in page view ( not in scroll), how do you get them to show up in page view. I can’t seem to find a way. thanks ...

Can you regionally change beaming style over rests? I know you can globally and somewhat with special tools. thanks in advance j
