Episode watchlist (to do list) showing how many unwatched eps you have for all shows

Please IMDB with all the streaming services it’s great to have a watch list but what would be helpful would be an episode watch list. Knowing you have 3 episodes left of this show and 5 of another. Not only getting the updates that a new episode dropped but having them as almost a to do list would complete my watching experience.

Like what Netflix and Hulu and the like do, but a central place where you can see all shows regardless of platform. With a notification badge. Mark eps as watched so you know where you’re up to
