As a non-coder I also find nano to be more than enough for 99.9% of my needs at the terminal. It's the first thing I install on a fresh OpenBSD (though sysupgrade(8) has likely made reinstalling that OS moot), and it's my goto for any non-Windows system I maintain.

Back in the early 2000s before I found nano, I used JOE on Slackware and loved it. I discovered nano and learned it, and now if I try to use JOE I find myself turning on its "pico mode" to get back to now-familiar commands.
