I was able to get over the majority of the style issues on Lemmy by adding the extension Stylus and installing this theme. https://userstyles.world/style/10440/rediggit-for-lemmy

Hopefully that helps some that want the old.reddit look.

Glad to see this. You’re welcome, enjoy!

One suggestion might be to load a Debian build on it and use it for docker containers. With docker containers you can do so many different things. I have a PI 4 and it does all of the following:
PiHole - For blocking ads. (Everyone should have one of these)
OpenMediaVault - For NAS
Portainers - For loading docker containers
Radarr - Downloading Movies
Sonarr - Downloading TV Shows
Tautulli - Monitors my plex server
Overseer - Allows members of my plex share to request content.
NZBGET and Real-Debrid Torrent Downloader Clients - For downloading content from usenet or real-debrid.

I have one Pi4 running all of these as docker containers. Have fun!
