Sorry to take this off topic but seeing as many here have developed their own markdown editors - I have a specific use case where I want to integrate a markdown editor with my backend (multiple technically unskilled users adding information in markdown, to render in html and eventually be pushed to mobile devices) I MUST HAVE a side-by-side editor (currently I use mark able.in which I have found satisfactory) but it doesn't have an api and often doesn't maintain scroll position.

If anyone is interested in making available their editor/working with me in implementing this solution then my humble startup could spare a few peanuts, please reach out to me(Python/flask backend, with PostgreSQL for persistence)
