It’s lacking some features yet — there are no preferences or choice of stylesheets for editing, preview, and exporting, no scroll syncing between the editor and the preview. But I think this editor has a lot of promise. Two things that I really like:- buttons at the top of the editor to switch between edit, preview, or split view easily, without having to go to a menu or remember keyboard shortcuts- ability to export as raw HTML as well as styled HTM — since I often need to grab content from markdown files to incorporate into web pages, I really like getting the raw HTML and not having to strip out style and class attributes.

The functionality is broadly good but the font in the markdown panel cannot be adjusted. It’s set at something quite small, which might make this app unsuitable for anyone preferring larger letters.

…but trying to open a markdown file with a ‘.md’ extension (from the Finder or the File menu) results in this error message: "The document “[FILENAME].md” could not be opened. md cannot open files in the “Markdown” format."
