- Yes you can do this at the album level or the track level. You would need to go to the edit menu then sharing and type in Explicit into the label field. And then you can sort, create playlists, restrict users by this label. It would be very cool if Plex Server would just scan for the word explicit or Exp or some specific word in the track file name and auto label it. or mark the track explicit in someway.
- Feature requests as far as I know you basically make a post. See this link Feature Requests
