Previous/next navigation

This was a great addition for content at reads like a book, which is a lot of documentation. However, this would be even better if you could customize the pages that are eligible for next and prev. Currently, it only works within the same level of the page tree. If you could allow it to go up to a customizable n levels up (or unlimited) for prev and/or next, this would be perfect!

Availablity as Server/Data Center app would be cool.

Nice idea, but configuration options missing (traversal levels, styling) and does not work with dark mode.

It works on same pages level.
