[idea] check items on friends lists
Lets say I am on a movie page, and I click on "lists" I'll get for example here: http://trakt.tv/movie/thor-the-dark-world-2013/lists
The given navigation elements are: "Personal" "Official" "Watchlists" "All" - of all members of trakt.
On those pages it would be fantastic to filter JUST the list of friends (or people I follow) - so I could see if he/she already has it on his/her watchlist or any personal list.
That way I don't have to recommend it anymore, when he/she knows it already.
