Nice work man! Clean, simple, easy to use.

This is fantastic. Just gave it a quick try to test it out and it seems very robust.

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

You guys should also try Atom text editor. It is also open source and comes with a great markdown preview package out of the box

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.
