If you are interested in a Markdown Editor App for OS X, Linux, and Windows (not browser based), which also support custom themes, and also supports emojis, and also supports GitHub Flavored Markdown and proper GitHub styles, then go star this repository of mine <https://github.com/niftylettuce/seuss.md> https://github.com/niftylettuce/seuss.md>. While I appreciate that this was built with React.js, it still does not solve the problem of the need for a better Markdown editor. I'm almost positive Mou still doesn't have GFM support, and MacDown still has 100% CPU issues.
