I think it should be an option, since sometimes one can put a film that was seen a long time ago in the watchlist to remember it again. I sometimes do that.

but only as an option!

This would be a great update!

You're right, Knaldskalle. Just tested it, and it doesn't work.

I guess this suggestion does make sense ..but afterall it is quite unnecessary.. as whenever u check a movie from ur watch list ,you can easily go to ur checked movies and remove them from ur watchlist. Would hardly take more then 2 seconds. :)

Actually, the "hide" function doesn't remove them. So if you come across a title from your watchlist that you've checked, you'll see that it still has that little + sign active.

Thanks for the tip, Sobchak. Maybe this setting should be on by default?

This can be fixed in your misc-settings: Hide already seen movies on your watchlist

Works fine for me.
