I did try jellyfin and I am using sonarr radar etc... Kodi with my choice of interface and plugins works very well and much more customizable IMO

You're probably right but I'm super technical and Kodi seems like too much setup even for me. I got the sweep above working in one evening. Jellyfin has a bunch of plugins too.
I used kodi since the xbmc days , and I switched to plex and then Jellyfin for a while. I went back because I was always missing those super granular tweaks I could do on Kodi that I couldn't find anywhere else.
