Goal: Ideate on better controls to bring back blocked tiles. Problem: Currently, once you block a tile (sponsored or a user's history tile), an overlay appears briefly to undo or reset all on the top left corner. Once that disappears, it's hard to bring back a blocked tile. This could be incorporated into the new tab cog option or some other method. Long-term purpose: The eventual goal is to have ad preferences built into the user's profile. This could be accessed in conjunction with the user's implicit interest signals (UP) and the user's explicit signals of not wanting to see an advertiser or interest category.
