It would be helpful to have a way to eliminate old alerts for items that are no longer on the wishlist.
One way to accomplish this would be to add a "not on wishlist" filter checkbox to the alerts page. Then we could apply that filter to quickly see which alerts are for games not wishlisted. From this point it would be easy to manage these alerts.
Also: It would be similarly useful to have a "not on steam wishlist" filter on the wishlist page, to help us manage the set of those games wishlisted on GG but not on steam. I realize GG has games that steam doesn't. Still, it would be helpful to see/manage that list.
