Mathematical LaTeX editing in Emacs with automatic inline rendering of math, tables, and TiKZ diagrams.
It's hard to imagine this getting popular because (a) it's Emacs, (b) LaTeX is a pain and Overleaf is pretty nice, (c) I think it would require the Auctex team to want to adopt my implementation, and combine their expertise and code to parse LaTeX math delimiters as reliably as auctex does, (d) I only use and develop Xenops when I'm studying maths, which is not much now I have a real job again. But Xenops is nice to use.
