Task scheduler Jellyfin + Unwatched Sync option

[bonnebulle]

Idea Overview
Jellyfin is my input of movies/shows
First, a task scheduler to sync Jellyfin should help (not having to go in settings)
Secondly, an option where is possible to see ALL movies/shows in Jelly
... so, I can evaluate all the catalogue + sharing it with others
