I feel like if yiu want a fully featured IDE with language highlighting, debugging breakpoints, and code completion, but at the same time you want more ergonomic user interface, you should just use VSCode instead of doing everything in the terminal

As the author states, this is for people who do most things in a different (modal) editor and just need a terminal editor on occasion.

I wonder which sort of features they could have in mind, if learning the basic modes is too hard for the intended user of the plugin.

They mention that as well - syntax highlighting is one example.

nano of course has syntax highlighting, so I’m curious where it falls short.

Does it have syntax highlighting for the same amount of languages as vim does, out of the box?

I just installed nano-7.2-1 and opened a HTML file with `nano test.html` and it opened without syntax highlight, I can see the point in authors endeavor if syntax highlighting out of the box is what they're looking for.

I mean vim does the exact same thing; you have to turn on syntax highlighting…
