[e.k.]

It is an option my drumer speak about : with pedal switch, imagine to display or remove notes of the active musicscore ?
Sometime, musicians have notes to remember, they don't need to display it all the time.  ?

IMHO there is no need for an additional option/feature like this.
If you don´t need your notes, just ignore it. Or, delete it (in preparation of rehearsals or stage or whatever).

Further, there is an option "show notes when loaded", check/uncheck it, as needed.
