Feature Request: Extend support for Markdown files

[RustyKnight]

Really like the idea, looking forward to playing with it.

One thing I do a lot is maintain a ChangeLog in markdown format, I tend to write my comments in Word, spell check them and the copy and paste them into the ChangeLog file, which is a little bit of pain when you just want to make quick, rapid updates.

I would be super cool to see the concept expanded to support mark down files. I have no idea if that's feasible, just wanted to throw it out there as an idea
