The "Always Open" checkboxes in "Edit String Data"
I'm having a look at this "Edit string data" dialog in Stave/Part properties for plucked/fretted instruments and am wondering if anyone here could supply any real use cases for the "Always open" column?
I could think of one (incidentally, from my own experience):
When arranging music for early plucked/fretted instruments. E.g., someone has given me a score for 7-course lute, and I want to arrange it for my 7-string guitar (which happens to have a ‘floating’ 7th bass string). I can simply check this box, and almost all of the manual redistribution of notes from the lute’s fretted 7th string happens automatically (and notes that can’t be played on any of the other strings are highlighted).
This is, admittedly, pretty niche.
So I'm wondering if there are other (less niche?) use cases out there that I haven't yet considered.
Please note: I'm only interested in the functionality of the "Always open" checkboxes, not any other functionality afforded by this dialog
