When Plex screensaver kicks on and the movies/tv shows are being displayed, add an option to “Go To” or “Play” current title. This could be a message displayed in the corner that the titles display. By hitting the option, your current movie/show would be in your recent plays and you would be able to go right to the movie/show that peaked your interest while on screensaver. I can’t tell you how many times I see something scroll by on the screensaver and think I would like to watch that but forget about it after I resume viewing.
This would be an amazing quality of life improvement. Hopefully it ends up on someone’s radar eventually!
