The Linked Pages plugin allows links between posts to be created using customisable page pickers and then displayed using the built in widget.
Making use of custom post types, you can now easily create collections of pages and include structure. For example, if your site is about football, you could implement two custom post types. Football clubs and Players. Using the provided tools, you can link players to their club in seconds and display the clubs current list of players.

This plugin seamlessly extends the post listing (edit.php) search functionality, allowing administrators to quickly find content based on values stored in custom fields.
It works out of the box with no configuration required—just activate and start searching. 
Especially useful for sites that rely heavily on custom fields, such as those built with ACF or other meta-based data structures.
Lightweight, efficient, and fully integrated with the native WordPress admin experience.
