Add "where" and "with" fields
It would be nice to be able to indicate where and with who has been seen a particular movie/episode. In particular:
 Every "watch date" should have its "where" and "with".
 In the "where" field I can write what I want.
 In the "with" field I can write what I want or add a trakt user.
 If in the "where" field I enter "Sunshine Cinema", this place is automatically saved in a specific "Places" page, in which I can add/delete/edit all the places.
 The places in the "Places" page are automatically suggested when I set the "where" field of a specific movie/episode.
 If in the "with" field I enter John", this person is automatically saved in a specific "People" page, in which I can add/delete/edit all the people names.
 The people in the "People" page are automatically suggested when I set the "with" field of a specific movie/episode.
 In the settings should be added a privacy option to restrict the visibility of these fields ("Everyone", "Only Friends", "Private").
Interesting idea, I think we could tap into foursquare or facebook for the places database too.

I've thought about this for a while. I have check-ins set to share with Facebook but the lack of people and places is a real shame. If I'm at the cinema I prefer to bi-pass Trakt altogether and use Facebook directly so that I get "Joe is watching This Movie at That Cinema with These People" rather than "Joe is watching This Movie via Trakt".
@OldTimerToo It seems pretty obvious that if this feature will be introduced it will be optional, and probably with some privacy settings (see the 8th point).
Personally, I do not like this idea. For one thing, that is getting far too personal, in my opinion. I'm an old timer and my privacy is important to me. No one needs to know what I watch, when, where, or with whom (my wife). We watch most shows at home from DVD or captured with Playon and saved to disc.
If something like this is added, then it needs to be optional and not required, but personally, I think this is publishing far too much information to the world.
 Statistics about "where" and "with" fields. The person with whom I saw more movies/episodes and the place where I saw more movies/episodes. And maybe other similar statistics (about times, total length, etc.).
