I don't know if it's bad form to do feature requests on HN but having gone through a lot of these note clients (see list [here](https://news.ycombinator.com/item?id=13642527)) the three-ish features that I'd like to see on a note client that can, but does not have to, sync to the cloud and that I couldn't seem to find in a single one are:

* Support for LaTeX math notation (like Zim-Wiki) * Support for code (like Quiver) * a good, clean UI if possible with a dark mode so that I can stare at it for long periods of time
