We discussed moving the complete button up into the navigation bar, like in the notes app, didn't we?

Another option could be this hovering bar like Safari does in web forms, but that's a lot less ideal than the Notes context-sensitive button in the top right.

@amiantos If we want to have the editor accept changes as final with checkmark and back button cancels the changes, then we can move it to the navigation bar.

In Notes.app the checkmark just closes the keyboard, it's not necessarily a save button, it just collapses the keyboard so you can see the full note content. I'd think we can do that here, too?
