Really close to being exactly what I needed, but not quite there. The biggest problem is the big "Block this page" button that appears under every page. Other blockers I've used have a much less obtrusive button on the side, or in a triangle drop-down menu. (I tried the "compact" option, but that just gets rid of the button entirely instead of making it less obtrusive.) But the real dealbreaker is that it displays the button even for webpages that have already been hard blocked and are not visible in the list.
