Adding Notes to to multiple notes and chords
So this seems like a no brainer.
1. The command "Shift + Note (letter on keyboard)" adds the note only to a single note or chord, even if multiple chords were selected. It really should be possible to add notes to the list selection and range selection of chords.
2. Functionally similar command of "alt + number" adds the interval corresponding to that number already does that for list and range selections, so this seems pretty logical, that adding note should also be possible like that.
