Key signature selection mode - alternative to dropdown

[b-cheek]

Regarding:

Key signature drop down

I think key signature might be cumbersome as a drop down because of the amount of options, especially using the staff indicator showing flats/sharps. What do you think is a good alternative? I think just typing in the key signature (e.g. "Ab," "F#") and then having maybe a major/minor radio button option is easiest, and we could also possibly incorporate the number of sharps/flats or the image of the key signature on the staff alongside this when the key signature is selected.

I think you're idea is fine- no need to display more than one key signature at a time
