Things I hate:
When you load a text/plain into a web browser, press ctrl-s to save it, and it decides to re-request the data from the server because it's supposedly uncacheable. I don't care if it's uncacheable. It's in my browser frame. I can see it. I can scroll up and down through it. I can cut and paste it. Why are you reloading it?
ssh+2FA to all your machines, anywhere, without opening firewall ports.
