Dedicated watched list of finished titles

Add a dedicated watched list next to the watchlist, containing all titles (both movies and shows) that have been finished. History serves a similar purpose, but sorting doesn't work there and especially shows are displayed per episode. The watched list would only feature show titles, no seasons or episodes, with all the regular list sorting and filtering options so previously watched content can be browsed — for example to quickly remember a forgotten title or to pinpoint which previously watched content to add back to the watchlist to rewatch in the future. When difficult to implement, proper sorting options in the history sections would probably work as well, but the single episode instead of full show problem would remain. Since all the data is already there, an automatic list filled with watched content seems like an easy and quick fix.
