GitHub flavored markdown would be appreciated. A way to export articles in Markdown or the "code view* for when an article's content needs to be replicated at another location.

Edit: Someone else already mentioned export feature — sorry for the repeat and noise!

Great to see this is now 'planned'.

Bonus points if you include support for some of the most commonly used things like admonitions and code blocks, as well as some key PyMDown extensions that are highly beneficial when writing documentation. In particular - keys, superfences, and tabbed.

This would be huge. I'm coming from GitHub/Confluence world and was surprised to find no Markdown (GitHub flavored or otherwise) support! Ability to export in a sane format is a must.

Still needs to be easy for those without MD experience to work with, but yes this would be great. All of my current guides are on an internal site built with MKDocs so markdown import of articles would be super helpful!

Throwing my support in on this one as well. Markdown would be so much nicer than the current rich text system.

Yes, and be able to export them to markdown would be great.
