I like “edit staff label” very much. It’s much more powerful than in other scoring-apps I know. But in some cases I would prefer different staff labels (instrument names) in score and parts. If I write a score in C I like to write “Bb-trumpet (sounds as written)” in the score and “trumpet in Bb” in the parts. Wouldn’t it be great to have the choice between several names for the same instrument - not only between full name and abbreviation?
