it saves the changes made to notes as you back them. the note app only discards notes you trash or erase fully and back page to the notes home page. I don't use mine a lot but I'm pretty sure that's what it does now, for me it does anyway. got the app synced to the cloud and one drive so the save as in a different format can be read else where. go to your note app menu and select manage folders, make a bunch with your titles, and then you can simply press and hold any note from the notes main home screen and then select move and deposit it it that folder to clear up clutter and avoid multiple copies. then to change a note, go to the folder and select it, make your changes and blackout should be changed.
