The most interesting new feature to me, beyond the UI itself - there's now some algorithmic generation in the movie/TV screens. It looks like the Movies screen will automatically offer up unwatched movies with recent release dates, as well as groups of unwatched movies from the same director ("Top movies by ..."). If you actually go into a movie and open the Extras menu, along with trailers/features (if you have a Plex Pass), it'll show you other movies by the same director and with the same lead actors. Similarly, the TV screen has groups for recently aired TV episodes, and even has shows grouped by the channel they're currently airing on (!). It's a neat use of metadata, and it would be interesting to see it go further. It would be really neat if I could, say, choose Star Trek TNG and get an automatically generated list of the best 10 episodes (with data pulled from thetvdb, IMDB, etc), or if I could go into Movies and choose an option to group movies by randomized Netflix-like specialized genres.
