out of the box it did exactly the thing I wanted: markdown with latex math expressions rendered.

thank you, very nice!

Pretty good! It doesn't interpret HTML, bummer. I'm running firefox for Linux, it didn't automatically update when the page was changed. Outside of those few quirks, it's fast easy to use and works with a number of markdown add-ons. I particularly like the TOC it generates in the side panel based on the headings.
