This suggestion is for the ability to set a key signature for your song (I.E. D minor, F Major, B Melodic Minor, etc.) which would then make notes placed along the different sharps/flats of the scales automatically set, rather than having to hold CTRL/SHIFT to make accidentals.
Along with this, you should still be able to use CTRL/SHIFT to place accidentals in a scale, for instance, say you’re in B-flat Major, but you want one measure to have D-flat as an accidental, you’d still be able to do that.
