If this had TeX I'd be interested immediately. There's no great way at the moment to mathematical notes, it's a big pain point.

Obsidian has LaTeX support out of the box. And there are some awesome plugins to make it even better, check out https://github.com/artisticat1/obsidian-latex-suite.

I didn't like Obsidian's TeX support very much. Primarily because it is very difficult to get macros working (especially across files). There are some plugins that try to do it but when I tried they didn't work very well. And anyway the features I'm interested in are sharing, collaborative editing, and having a good way to present things that are typed up.
