Great add-on, always the first I add to a fresh install. That said...
A "don't show me this" option, in the style of No-script's "untrusted" tab.
Using this add-on, it's pretty common to go to a page with, for example a blocked embedded video, there will be 15 different things blocked, 2 will be the things I want to allow eg: youtube and ytimage and the remaining 13 will be the usual advertising + tracking crap that I never want to allow.
It'd be real nice to be able to move these regular offenders to a separate list, it'd make temporary whitelisting so much quicker and easier. If you incorporate a "temporarily allow all that aren't added to the blacklist" option as well, I'll name my first born Justin!
