Is there anything like Roon for movies? If not shouldn’t there be?
Plex is very good for movies and TV shows.
I use 10muse for a couple of years now. 10muse is developed by one guy and as soon as there is something he picks it up immediately. He also very open to feedback.
It is very lightweight and may lack some of the bells and whistles other progs have, but to me this a bonus.
I use the iPad app together with my Dune mediaplyer. It also has KODI / HTPC integration.
All depends on what you are looking for.
