Sometimes I want to go back to an older piece written in hymn style (chords on two staves) and rewrite/alter it for multiple parts. The obvious way to do that would be to select all the notes of one voice, copy them, and paste them onto a new staff. Not possible. Even though Copy/Paste are "permitted" (not grayed out) in the dialogs, it doesn't work; nothing gets pasted. Likewise with Ctrl-C/Ctrl-V. I hope this functionality can be added in the upcoming v4.
Once they're all selected I can cut (Ctrl-X) or delete (Del) them; why not copy/paste? Or maybe copy works but paste just doesn't. But then why is it apparently permitted in the dialogs? Copy/Paste only apparently works if I select a contiguous range of notes. But if I select those same notes individually it doesn't.
I can understand why it might not work if I were to select disparate and non-contiguous items and try to paste those (though it seems even that should be possible if I were so stupid), but isn't a "range" of individually selected contiguous items the same for pasting purposes as an actual range selected only by first and last?
If it can't (or shouldn't) be made to work in this way, how about another approach? In More... within the Select dialog how about an option to select all similarly-placed notes of a chord? (Meaning, all the top notes, all the middle notes, all the bottom notes, etc.) You'll say, select all the notes in a single voice. Yes, if it was written that way. But if it was written as chords in a single voice that doesn't create the desired selection.
But even there, that sort of selection is a mass selection of individual notes, not a range selection, and copy/paste doesn't currently work for that either.
