What does HackerNews think of nano-emacs?

It's not adhd specific but https://arxiv.org/abs/2008.06030

After reading this I implemented a code theme based primarily around typographic variation like weight rather than color. It uses only two colors (black and deep purple) in two weights and one italic each. I have pretty severe adhd and it's hard to judge but after using it for a few months I think this is better for me. Previously I had been using solarized light for nearly a decade for probably similar reasons.

Nano emacs was created by the author of that paper and its default themes are based on it, if you want to try it without committing to hand-rolling a theme. Personally I found that one too "light" (typographically, not color) but I also have relatively poor vision and like a large and heavy font.

If level of customizability is your main metric:

Emacs can go from this: https://emacshints.files.wordpress.com/2013/09/spash1.png

Speaking of gorgeous themes I’m going to boost Mr. Rougier’s excellent work: https://github.com/rougier/nano-emacs. The rest of his portfolio is also well worth a look.
