First, a small bug. When I’m in this mode
changing the note duration using a shortcut key doesn’t change the grey notehead until the cursor is moved. So if I’ve switched from a crotchet to a minim (i.e. black to white) or the other way round, the grey notehead will still show a black note even though what will actually be entered when clicking is the minim.
And a feature request: Like Finale, it would be better to display not just the notehead in grey, but an entire note. That way I can see at a glance – without having to double check in the note-entry panel – whether I’ll be entering a quaver or semiquaver, etc. Currently, the notehead only tells you whether you’ll be entering a black note or a white note.
