Officially wasted an evening chasing a red herring of a simple markdown editor. There are very few projects out there and all of the drag a full blown markdown parser, code mirror, ton of styles and optionally the whole web font in order to draw an enhance textarea, which sounds totally not compatible with the idea of keeping dabdab as fast and as light as possible.
The ideal component for dabdab would be very similar to what github minus preview tab, since the whole idea of a toolbar would be to have the buttons that would remove the necessity to switch the keyboard on the phone in order to find symbols to render a quote or a bold font.
The other awesome feature github has is their image upload functionality, I want that as well
