Add an "Undo" feature to the manual blocking wizard
Suggesting on behalf of a user:
1.clicked ad to block
2. slid the bar just far enough it looked all good
3. now it's blocking pictures in posts, not just the sidebar ad pictures/text.
it should have only blocked the frames that showed being blocked before I clicked LOOKS GOOD
it doesn't look good now, it's blocking MORE than I wanted it to. I don't want to "UNDO ALL" blocks on this domain, just would like to undo the LAST block
