In WordPress, a page’s parent or the categories of a post typically influence the final permalink/slug URI.
When editing a post or page in the WordPress admin backend and changing any of these, the preceeding URI parts before the slug below the title input don’t get automatically updated though – pretty confusing.
This simple extension automatically reloads/refreshes the permalink preview URIs when having selected different page parents or post categories.

Adds a filter in your wp-admin that allows you to choose a parent page so that only the children of that page will be shown. Very useful if you have a lot of pages!
