If you do end up trying it, let me know if you run into the issue of the UI constantly “refreshing” while editing and ruining your changes. I’m not sure how widespread the issue is.

You could check out expander card. I use it for a weather section on my dashboard.

Editing the card is really buggy for me and I’m not sure the project is still open, given the note at the bottom about the issue tracker… but after it’s configured, the card has been very solid.

I like the expanding room cards. Can you share how you’re accomplishing that?

I figured swap would only be used if I ran out of available memory. I’m not an expert at all, so I could be totally wrong about that.

Is it possible that the container is allocating the space preemptively but not actively using it? So proxmox would see it as being used, but plex is simply reserving it. I think I’ve seen that occur on other containers like home assistant (but this is a VM not LXC). Proxmox says it’s using almost all the memory available to it, but going into home assistant itself says it’s only using a fraction of that amount.
