Ask HN: Would you like a medium.com meets markdown writing tool? #mvp

Whenever I generated an html from markdown, I have the urge to do some final touch on page (adjusting line hight, making first letter bigger...), instead of just relying on the built-in theme that tool provided.

I was wondering would you favor a round-trip markdown/html editing experience, where you can focus on writing in markdown, and visually style the page as in medium.com then generate the final html page ?

Something like this: http://www.visual-marks.com/en/demo

Disclosure: I created this MVP, trying to verify if the above-mentioned tool does have value to you all.
