Thanks for this contribution, I really like the new sidebar!

Are there also changes in content, or is it only the structure that changed?
In case that is only the structure, I will approve it as it is :)

Just restructuring for now.

Add information about PEP-563, since we dropped py3.6 that should be something we can recommend.
See py3.7 changelog

No this a PR for restructuring only I’ll do additions in a later PR which I’ll pull soon.
