I’ll make a shameless plug for the Scyfin theme – Base + OLED. Looks wonderful and works quite nicely. I have Jellyfin and Plex running on the same machine, pointed at the same mount points for libraries, and using the same tmpfs ram transcode mount (110GB) for transcode duties. Since I’ve moved transcodes off of the same SSD with the DB, things have been FLYING. Give it a whirl.
