That's a lot of plugins! I guess we should discuss which ones will be useful but let's just go by them one by one :)

@knmcguire Sure, and I already left some of those out, haha. We can even propose a priority system for these, that goes according to our needs, as consumers, writers, and developers. Maybe, we can start with the ones that create a solid base for the rest.

Here is another nice catalog of different plugins here as well: https://github.com/mkdocs/catalog. It's a lot but might be a good recourse
