Watched-list. Easier way to keep track of seen movies.

Please create a Watched-list button (history-button) next to the Watchlist button on the movie pages.
There should also be a "seen" button on the watchlist. When you click it the movie is automatically moved to the Watched-list
This will make it easier to keep track of moveis you have seen and movies you want to see.
This way don't have to create a specific toplist to keep track of the movies you have seen and you dont have to search for each movie on that site.
