"Advanced Usage" - split into separate pages for the sections, or at least provide links to the sections

[klartext]

The one document I look up the most is the Advanced Usage page:
https://neomutt.org/guide/advancedusage

That document has 19 sections and goes over 31 screen pages.
Looking up something by String-Search of the browser often leads me to the wrong section.

I would like to have separate documents for the sections, so that a string-search stays inside the current section.

The minimal change I would like to see is to have links to the sections of this document,
but I would prefer to even have separated pages for the sections.
