One of the best markdown editors I’ve used… when it works. After reinstalling it on my work machine, it stopped rendering markdown. But other than that, this tool is a champ. Fast editing in a split pane. Type in to the left side and it’s rendered out on the right. It even supports GitHub flavored markdown, so you knwo just how your README’s and project wiki entries will render.

Despite the issues, I’ve gladly shelled out money and use the licensed version of this app.
