Nice, but the input box needs to be much bigger. We sometimes have very large multi-line equations say
 * $$\operatorname{atan2}(y, x) =

\begin{cases} \arctan(\frac{y}{x}) & \mbox{if } x > 0\\ \arctan(\frac{y}{x}) + \pi & \mbox{if } x < 0 \mbox{ and } y \ge 0\\ \arctan(\frac{y}{x}) - \pi & \mbox{if } x < 0 \mbox{ and } y < 0\\ \frac{\pi}{2} & \mbox{if } x = 0 \mbox{ and } y > 0\\ -\frac{\pi}{2} & \mbox{if } x = 0 \mbox{ and } y < 0\\ \text{undefined} & \mbox{if } x = 0 \mbox{ and } y = 0 \end{cases}$$

I also get wierd interface errors if I have my preference set to math_png and try to edit the large equations.

Is this related to Jiabao Wu work or something different?
