For quick self notes I use Markdown. I found most rendering engines support $math$ these days. Either that or pen-and-paper/tablet/remarkable. Joplin is fantastic for creating and organizing references as long as you don't need advanced layouts. When you need them you can very quickly convert MD syntax to html or latex. On a side note I always wonder who has the time of fine tuning uber-specialized text editor configuration at those levels. Not only that, but also having the burden of maintaining that and the inconvenience of being dependent on a very specific setup. I could see myself doing such an effort only after 4-5 years of daily use and friction.
