Might you be able to make ornaments and playing techniques move when using “cross to stave”? For example, trills, mordants, M.S./M.D. etc? Either when the associated note is moved or when ornament is selected and M/N keyboard shortcut is pressed?
I see that you can delete a note and the corresponding ornament/playing technique is not deleted as well so I guess they are tied to a stave position, rather than to a note.
Of course, I can get around this in Engrave mode but it seems they should move.
All in good time, of course…
