Playlist problem

Hi. I am coming from Plex and seem to not be understanding playlists… I used to use them to keep a list of the movies I wanted to watch next. I would see something on eg. my friends plex server and would add it to my “Watch” playlist. When I was next bored I could then look at my playlist and watch something from the list → once I had watched it I would remove it… Is there not a way to do this in Infuse? I can create and add movies to the playlist, once in there I can see whether I have watched them or not but I cannot seem to find a way to remove them. I have tried on my iPad, my AppleTV and infuse on Mac, what am I missing? Thank you for any help given
