Already in my collection?

When viewing search results and lists of stuff that is not mine it would be nice to have some visual indication to see which of the items in the list that already are in my collection. Maybe some kind of icon or a different background color or something?

I used to have this but it slowed down the search queries, I would like to add it back at some point.

Sorry, must have been before I came onboard. Yeah I kinda figured that could have been the cause, you'd have to join the 'all movies' and the 'mine movies' data sets or something like that? Well if you ever find a way to do it it would be nice.
