Is it, though? I’d argue that nano is the most accessible, easily discoverable, and usable editor for simple text editing available on almost any Linux system out there.
It’s no IDE, but it never claimed it was either. It doesn’t require a manual, as even the shortcuts are shown at the bottom of the screen for reference. And it includes syntax highlighting, tab handling, and basic cut/copy/paste handling.
What is it you’re missing from a standard text editor?
