Feature request for some future update…
Give some way to make octave lines apply in the score only. Either a toggle in properties, or perhaps some more general “show in score only”.
One thing I’ve read in quite a few places from e.g. flautists is that they are perfectly comfortable reading 4 or 5 ledger lines and it’s easier for them because it doesn’t interfere with muscle memory. Whereas in the score 8va notation is often more or less compulsory so as not to waste precious vertical space.
