Itex

With the (default) Markdown+itex2MML filter, you can enter equations in itex, a LaTeX-like dialect. Inline and display equations are supported, as is automatic equation numbering and other such niceties.

Here’s a simple example:

 \[\label{Gaussian}
    {\int_{-\infty}^\infty e^{-a x^2} d x} = \sqrt{\frac{\pi}{a}}
 \]

(This feature is coming soon, and when it works, the following will look good)
