Hello! Is there any way to edit/rename or delete added custom tunings? For example, I'm trying to edit a tuning called "Eb Standard" (wrongly set on 6-6-6-6-6-6, which should be Bb), but ,after renaming, even when I press ok or add the check on "Add as new tuning" nothing happens. Also I have two "B standard" tunings in the list, and I want to delete one of them. How can I do? Thanks!
