Filtering for third-party resources without explicit domain

When trying to filter for third-party resources “” (negated filtering by properties).

While that is possible, it requires to actively change the domain manually. I’d like to suggest expanding the “is:” flags with “is:third-party” or even “is:third-party-host” and “is:third-party-domain” (and “is:third-party-remote-ip”?).

In the same spirit, I’d find it useful to also have “host:” in addition to “domain:”.
