Disallow editing if 'Hide Empty Staves' is enabled?
Hide Empty Staves may cause problems if enabled during editing.
A few months ago, I did suggest this .
However, I think another good way to solve it would be to disallow certain (or all?) aspects of editing - treat 'Hide Empty Staves' as if it is to be applied once finished.

I would normally leave that option on while editing parts that involve multiple stavrs, so I definitely would not the program to arbitrarily tell me I can't do that. Better to simply fix whatever bugs that may exist.
