Having a note in both default and custom widgets will help a lot for both web users and admins.
Example 1: Web editors (non-admin) may not be aware that they’re editing the shared asset (even it’s under their workflow and is accessible) but it’s affecting the other department’s (outside of their workflow).
Example 2: Can leave a note about a reminder, like don’t forget to change the link once a month or inform this person if you have any questions, etc.
