Feature request: MathJax support for editable slides

[juandodyk]

Hi! Amazing work.
It would be useful to be able to write LaTeX equations in editable slides, to use those slides as a kind of blackboard.

A design challenge is how to move between latex and rendered equations. Ideally one would double-click an equation to edit the latex code ("un-render" it with double-click, edit it, and then "re-render" it again somehow). An easier solution is to have two panels, one with latex and the other with the rendering, like this.
