Use the shortcode [private-user-notes] to any page or anywhere to turn it into a user private note page or section. Users will be able to add private notes there using a rich text editor. The notes are only visible to user himself as it’s private right! 
It also gives user option to print their private notes with a single click.
This could be really useful for membership sites where you might want users to be able to save private note in any page,tab or their profile.
Admin can control who can use this feature and be able to save private note. It provides a plugin settings page under Settings inside dashboard where access settings will be found.
