I am closely watching the new Sonarr fork for movies (Radarr) and Watcher. I am also not a fan of CP (especially the API).

If either of them look like they'll stay supported for a bit, I will add support into nzb360.
I've been playing with Radarr over the weekend, and although it's got a long way to go, it is functional, so if Radarr could be added to NZB 360, I'd use it a lot more.
