This is fantastic. Just gave it a quick try to test it out and it seems very robust.
Nice work man! Clean, simple, easy to use.
Honestly what gripes me the most with Mou/MacDown is the lack of tab support. Hopefully that could be addressed soon enough, since having a plethora of windows open is overkill.
There is also LightPaper, which comes with tab support and is also free.
+1. Been using LightPaper for a few months now, and it's perfect for my workflow. MacDown is fairly nice too though. Haven't had a chance to mess with it a lot just yet.
I'm going to say it:
I hate markdown. Why when I know HTML do I want to learn another way to code links and font styles? Why on earth?
Everytime I want to share a link or make a list or do some bold font stuff I have to read a markdown guide. It's annoying.
Why the human brain needs to make more room for another language. If an input supports rich text it what's wrong with providing a WYSIWYG bar? God forbid we do anything intuitive less it mess with the minimalist design of website text forms everywhere
