Comment 6 for bug 1685445

At CPT Jan 2019 we discussed UI to:

- clear an individual device from the list
- clear the whole list, and force it to rebuild

Transient interfaces, e.g. phones might never be seen again.

Obviously devices still on the network will reappear at next scan. Clear and "suppress" this interface would require us to track and manage a list of "things to keep hidden" which seems baroque and unnecessary.

We also discussed if the auto-scrubbing "Devices seen in the last 5 days" should be on the controller, or could be a function of the UI, and tended towards the former.
