The Studio Dashboard has a Notification Indicator that shows a Number.
The problem is there is no way to determine what the notification refers to. It may be useful to add a System Notification Section to the Dashboard.
That way UNA can add some semblance of a note to these notifications. What has been updated or needs to updated, new releases etc. Actions that need to be taken by the Operator(s). ...

Next Scheduled automatic system update time etc.

 eg. I have a 1 on the dashboard, but the Updates section is empty, all relevant updates have been applied.
