How about nano? It's very simple. https://linuxize.com/post/how-to-use-nano-text-editor/

Definitely recommended, and available on nearly every platform.

I think Sublime Text is pretty simple https://www.sublimetext.com/. I still use version 3 because it's enough for me. You don't have to install any packages, can hide the sidebar (I do); just have a simple window.

Regarding autocomplete, I made my own. You can add files which contain only the words/keywords you want.

This is looking very good, thank you!

Barebone VSCode is pretty minimalist. You can also hide everything in the side/bottom toolbar. Remove minimap and tabs, etc.

Gedit or nano. But I’d just learn the basics of vi/vim, as it’s on every *NIX system.
