An oft-requested feature has been the ability to edit a note you've entered to fix a typo or correct a category. That's now here!
If you authored a note, you can now edit that note from either the person's profile or from the Notes Dashboard. Editing includes the text of the note, the date, and the category!
The notes interface received a smidge of a facelift to make this possible, so if you noticed the change, kudos to you.
Happy Noting!
