Plex Hidden Settings on TrueNAS Scale

Plex has hidden server settings, Advanced, Hidden Server Settings | Plex Support I’m trying to adjust my settings for my video preview thumbnails, Big Media folder? Make smaller video preview thumbnails! - Tips, Tricks & How-Tos - Plex Forum how do I do this? I have everything else running the way I’d like pretty much on my TrueNAS setup but I can’t seem to figure this out. Can anyone else? And please note I’ve only been running TrueNAS for like 2 weeks now so a lot of this is new.

Bonus help if you can, how do I access my plugin folder in Plex so I can install custom plugins?

For real, big thanks to anyone who can help

If you want to access your plex folders you have to use hostpath with a predefined folder. I use one like this “/mnt/apps/appData/Plex”

otherwise the IX-applications will make data sets for every application you install.

What custom plugins would you install?
