This is great, thanks for sharing!
It's funny, I was just thinking about trying to use Electron for a markdown editor project.
I work in an academic environment and fantasize about luring writers and editors away from MS Word into Markdown. Unfortunately it looks like the Marked library (the most popular JS parser) doesn't support extensions like footnotes, which are critical for my use-case.
My ultimate dream would be to have an Electron-based markdown editor that supports inline "tracked changes" through something like git.js[1], sort of like a desktop version of prose.io.
Care to share any thoughts about the experience of working in the Electron platform?
