Spike: Can We Use Automated Nav Instead of Manual

[eukota]

The Nav/Pages config in mkdocs yaml file can be maintained manually or left to automatically scan the documents. We should explore letting it be done automatically.

Questions

• can we control page listing order without having to list all pages?
• can we modify the displayed name in the nav dynamically via some option in each markdown file?
