Filter devices with no name or regex

[0ge]

When I do a scan in the office environment, I get 35 devices with the name "<Unknown name>" (presumably their name is not advertised).

It would be really great if there was an option to filter the list to remove these devices. (I.e. only named devices appear in the list)

For us, the best solution would be to allow regex filtering, so we can for instance do ".+Test.+" to filter devices we're developing to, or ".+" to filter named devices.

For other looking for this I discovered that you can at least use | to filter. E.g. A|B will display names and addresses that contains either A or B.
