Using front matter to drive navigation placement

[desktophero]

Love the updates and approach to awesome navigation from the project.

Sort of similar to #85 but not looking to take actions like sorting.

Sorting was called out as not possible so wanted to see if frontmatter is either an existing option or something that would be of interest for a roadmap item and contribution.

I have a use case where I want to be able to use frontmatter to set a status for a particular markdown file. The purpose of the file is an architecture decision record. I would like to have an ADR section in nav and then be able to place the same rendered page into different navigation sections.

I see how I could sort of do this with filename regexes but that sort of has a smell and would be harder to reuse the metadata.

An example would be something like:

---
status: accepted
portfolio: commercial
<snip>
----
Markdown content

And then have navigation for both portfolio and status that would link to the same page. But navigation would look something like:

- ADRs:
  - All ADRs
  - By Portfolio:
    - Commercial
    - ...
  - By Status:
    - Accepted
    - ...

I'm happy to hear that you're liking the plugin!

You present an interesting use-case, although I'm unsure if this fits in the scope of this project.
One big change to how the plugin currently works is that it would have to produce duplicate entries (the same ADR listed under All ADRs, By Portfolio, By Status). The filtering by frontmatter would also add quite a bit of complexity.

Have you considered using the blog plugin from mkdocs-material for this? It might not be exactly what it's designed for, but I think it could work.
