Nice to have: allow all subdomains by wildcard, by a click of the mouse

[xgRTHKk4]

When a host is blocked, a menu item appears in 'Recently Blocked'. You allow it. Then another subhost appears. You allow it, etc. Then you decide, ok, I'll edit the rule to *.domain to allow all hosts. I guess this is what that rule editing dialog is for at this moment. Editing the rule would not have to be necessary (could become optional), when an extra menu item would be added to the left or right, 'Allow all subdomains'.

You could decide to make it fancy by giving extra options in the case of many sub-sub domains, or choose to only care about *.domainname.tld ('enough for most people').
