Add a "Watched" List

It would be nice to be able to quickly move a title from your "Watchlist" to a "Watched" list. It would make it easier to find a new film to watch if I didn't have to navigate through ones that I've already seen. Maybe even add the ability to automatically switch it over upon giving a film a rating. I realize that I could make a custom list but I would need to navigate to the page of each film to do that and I have over 3000 films on my watchlist just to change it. Maybe add a button or dropdown on the watchlist to be able to easily move a title to a different list so it can be done all from one page.
