I'm curious what input method you've found for unicode maths, most of it seems to be input via various TeX-like DSLs (e.g. mathjax), or people just take photos (or screenshots of the TeX and paste into powerpoint...)? Also, (La)TeX gives you a good-enough environment (especially with something like overleaf for sharing) for maths+crossrefs+citations that I'm not sure you can go simpler (I've tried with markdown and rst, but both end up being more of a pain, and the more maths you have, the harder it is to go without macros). Modern word remains a issue as I found out today, and most other word processors have even less support for throwing something vaguely academic together (i.e. with LaTeX I can just start dumping in content and refs and maths just work).
