I’m not sure I understand why, but if I choose Add note in the Sorter and start adding, if I hit CMD+S, which is SAVE in every other Mac program, I get Clear. I was working on a long note and muscle memory hit CMD+S and boom - gone.
Which version are you running? Pretty sure I remember reading somewhere [edit: in the future] that’s been fixed but I don’t see it in the release notes [edit: yet].
