Support for MathJax

[amonras]

It would be great if there was a way to support MathJax. I suppose it should be fairly easy since one should just add the MathJax JS in the header and some dedicated css hacks. The tricky part would be to switch between LaTeX compiled and LaTeX source code when one clicks on a text box.

On a more general level, it would be nice if we could have some sort of markdown language to easily format text. The markdown parser from mathoverflow is rather standardized and opensource...
