Automatically apply accidentals
If I'm entering in arpeggios, key is C major, F sharp, A, C, F... I want that bottom F to automatically be an F sharp, even if it is a different octave. Would be nice to be able to specify in formatting as to whether I want courtesy accidentals on differing octaves, same measure or not.
It would also be really, really nice if, in the next measure, when I typed in F, MS automatically added a natural sign to it.
I often will write a line, copy it, paste it to another instrument, change the octave up or down and keep going - and all the courtesy accidentals get destroyed because of the octave change, and I don't remember or notice it because it sounds correct on playback.
Seems like a thing that could be automated.
