If you agree that moving Playlists off the initial screen is a bad idea, please add your vote to that thread (we shouldn’t split votes for the same feature across multiple threads).

To create a Smart Playlist, which should add new seasons/episodes to the playlist automatically, follow the instructions for Smart Playlists on this page.
