Subtitle plugin like in XBMC

Hi I have been using Plex for several years now and I just love it. Unfortunately one key function is missing which I experienced by installing XBMC. Bering a foreigner I prefer to have English subtitles on tv-shows and movies, and the function where you can search for and download subtitles for a movie inside XBMC works much better than having the mediaserver do the same, as often the mediaserver fails to totally recognize the movie and hereby no subtitles are downloaded.

I know several others who would love the same feature, and I guess that the function should be rather easy to port to the Plex system.

Please please please, and thank you for a great software.
Your media indexing rules big time compared to XBMC.
