Macdown: Open source Markdown editor for OS X

LOVE this markdown app.

I was a Mou user prior, until I upgraded to Sierra and Mou stopped working.

I'm very happy with this one. Feels very solid; Mou sometimes would take awhile to save a small file. Macdown doesn't do that.

The best Mac Os X markdown editor even though it's not perfect... I miss Mou on which MacDown has been inspired.
