Recently I started using vim because I wanted to use a minimal editor and got impressed with its plugin library and what you can do with it on the terminal.
The entire JetBrains family. I will go thru trouble to streamline my workflow and make it work with those IDEs. I refuse to code without them.
For quick editing I guess notepad++ on windows and vi on other platforms.
Just neovim. I'm developing a game in Godot and tried to use the built-in editor there, I couldn't bare to use it, when one sticks to the vim way of writing, one cannot live without the vim way of writing.
