I usually name mine after songs that I happen to be listening to at the moment.

Ranger, mostly for bulk renaming

A mouse is a must if you get a dock for it. Some emulator settings are impossible to get to with an external controller. Keyboard is also nice to have.

SD card obiously for more storage.

I use it for seeing/replying to texts on my desktop. It works great for that with xfce.

I would get a powered USB hub for your hard drive, then plug in the hub into your RPI4. The usb ports on the pi cannot handle a lot of power(from what I remember).

Yes, i have used tailscale. I just use wireguard alone because I find it has better performance in my experience.

Lemmy Jellyfin Wireguard so I can access my home network from outside

All three are easy to manage(so far).

My main gripe is with movies. After a while, the simlar video recomentaions are filled with “Free with Ads” movies. I don’t even watch movies on Youtube. Its annoying.

I usually have to clear cookies to get rid of them.

Grand Theft Auto 4 is awesome to play on the go(though it does eat battery life)
