I originally enquired about this at http://tex.stackexchange.com/q/162664 but misconstrued [Bakoma-TeX](http://tex.stackexchange.com/a/28389) as a Mathjax editor. Please advise if anyone objects to this question. 


<s>Barring [Bakoma-TeX](http://tex.stackexchange.com/a/28389)</s>, are there any other WYSIWYG editors for MathJax? 

To wit, I'm asking for a vaster WYSIWYG editor than that at Math StackExchange, with respect to https://math.meta.stackexchange.com/q/10505/53259. The tribulation on MathSE is that the preview panel is hidden below the input box. For desire of augmented productivity, I'm questing after a WYSIWYG editor in which I can view the preview/output on one monitor while working with the input on another monitor. 

I tried those at http://tex.stackexchange.com/a/28389, but they don't seem to pertain to MathJax? For instance, if I input text without $, then writelatex.com fails to effect the output:
