When someone is on their own report: Dashboard or Report Builder, they should have a new button (text button) that says "View Report Activity". Only admins of the report, or Portal Administrators can view the button. However this would give a great in-the-moment way to view who else is using the report, how much is the report being used and by whom. It can include: Numbers (frequency) and by whom it is being accessed.

* Views
* Creation
* Editing
* Deletions/Deactivate (still logged) - Deletions, as in removals from a Dashboard, making a report inactive.
