There is this nice idea for me that you have two buttons that stepwise change the ghost note in PBD (like in Finales Speedy Entry I think, though I don’t own it), like the + and - sign on the numpad, and still always have to last note you already entered selected, so you can manipulate it with Shift+I popover, to e.g. add an octave above.
If After inputting note is on, you can manipulate your last entered note, but you can’t manipulate the shadow note stepwise up or down.
If Before inputting note is on, you can raise/lower the pitch of the ghost note, but you can’t manipulate the last entered note with Shift+I popover.
So my plan is to write a script that when pressing the + sign on numpad, it temporary turns to Before inputting note, then it raises the shadow note one whole step, and then it goes back to After inputting note.
That is probably a not-understandable-word-salad
