It would be nice if the widget had a "Stale" category/panel/button that showed a count for computers that haven't reported DetectX status in over X amount of time.

To elaborate a little I think the optimal behavior would be to leave stale machines with Issues or Infections where they are until they report in as clean. But move computers (change the counts) from Clean to Stale if they are overdue for reporting.

This way problem machines will stay front and center for admins to keep an eye on while distinguishing recently reported clean computers and ones that are in a more unknown state at the current time.

If device reports in multiple times with issues or infections, the list keeps growing.
