There were a few posts on meta about choice of editors where to prepare posts - using MathJax + Markdown.

In connection with this, the following is interesting:

> There is recent overview of markdown editors for windows.

> I was searching for an alternative to Stackedit (which I had used for some time), simply because I missed basic file handling in the menues ("open", "save", "save as") and found, that Typora mentioned in the overview, fitted my bill (there are also downloadable versions).

There is a link to: The Best Markdown Editor for Windows

> In this article, I won’t be reviewing online editors such as Dillinger, Markable or StackEdit. My focus here is just on apps you can run on your Windows machine.
