I don't know why everyone is getting self-righteous about this. I've used Linux since the mid-90s, and occasionally I find it easier to just run a GUI file manager as root to do some filter and deletions of things in caches and such that need root permission. Hell, I want to edit the files in /etc/wireguard for my tunnels; should I only do this at a sudo prompt in the terminal when I'm perfectly capable of pulling it up in Kate and copypasting stuff in?
Get off your high horses, there's plenty of valid use cases if you're using your head.
