That looks good, I'd like something like that links list to be accessible from a click on the adblock A, in that case probably sorted on blocked/not from the beginning if possible.
I don't think I want clicks on the checkboxes to open an extra dialog by default though, if there are good and updated filters in place most of the time it should be enough to toggle that list. However, I still think that there needs to be a site+filter list, so I could block/unblock all "ad-company"s ads from "
site.com", not from all sites. With a good default, global blocks would be rare, I think, and covered by the advanced modes.
