[Feature request] Inverted whitelist

[atkrv]

User asked to implement to our iOS app the inverted whitelist that blocks nothing, еxcept that in the list. Just like in our extension.

Got a feature request from the Twitter.

This is actually possible (at least we were able to do this in the Safari extension).

Let's wait for people votes, does anybody need it?

I'd like to see this if my vote counts :)

If by inverted whitelist it's meant that it would block all resources except for (a) whitelist rule(s), then I vote yes. Although if I'm misunderstanding this due to my lack of seeing this (missing it?) in the FF extension on Linux, my interpretation would be accomplished simply by using the wildcard * to block all but what is given express permission by the user. Either way, yes.

It should be there, right in the "Whitelist" settings section
