In the Notes section, "Mark Note Complete" means:
Completion: You have finalized your entries in a note and consider it complete. This action prevents further edits to the body of the note to maintain the integrity of the information recorded at that time.
Further Information: While the note cannot be altered once completed, you can still add additional details through an addendum, which allows you to append information without modifying the original note.
This structure keeps the explanation clear and provides a distinct separation between the main action and additional options.
