The current functionality to hide staves seems to only provide the option of hiding a stave which contains empty measures for the full width of the page. Is it possible to hide single empty measures within a stave which have measures with content directly before and after them?
So basically, I would end up with a score with contains white patches where full measure rests are as well as whole sections where empty staves are hidden.
I can provide an example if this is unclear.
Cut away Scores are not currently nativly supported, but as far as I know planned for the future, whenever that may be.
You can use ossias or additional staff for solo players though, if the hidden measures are part of an existing player.
