"I" for instruments ... but where is the "Select ALL" / Select None" toggle for visibility?
In the instruments dialog box if there were a "Select All / Select None" button to Uncheck all visible instruments ... Right above the "Visible" box would be perfect ...
so we could just select one or 2 or what ever, rather than unchecking every box all the way down
one at a time ... until we find the 2 that we want to see at the same time, and only those 2 ...
It would be very quick and easy with a button like this.
Then ... If we could save that ... let's call it a "Lens" ,,, and name is as let's say
"Bassoon + Clarinet + Flute" we could switch to any user Lens we've created and be able to edit just a very select part of a score.
Then of course go back into "I" and uncheck the lens and be back to the full score.
