I'd love to have a filter available for IMDB watchlist. If I could plug in my credentials to Plex so in a Plex player I can filter my movies based on my IMDb watchlist that'd be great. I often use IMDb watchlist as my go-to when someone recommends or mentions a movie or if I decide I want to re-watch a movie I have.
Have a look at CouchPotato. This movie downloader (with support for both usenet and torrents) can use IMDB watch lists. Once checked on IMDB.com, it automatically adds the movie to the wanted list in CouchPotato.
