Different Single Post Template per Category
Lets a classic theme use single-cat-{slug}.php for posts in a given category, for example a recipe layout for posts filed under Recipes, falling back to the normal template.
Snippet Library
Developer snippets for WordPress
Snippets for developers: debugging helpers, custom cron schedules, body classes, REST API tweaks and admin tools for checking hooks and queries. Building blocks for people who write code for WordPress every day.
Image Sizes REST Endpoint for Headless Front Ends
Adds a public /wp-json/site/v1/image-sizes endpoint listing every registered image size with its width, height and crop setting, so headless front ends can pick the right size for each layout.
Read-Only Custom Fields Viewer for Administrators
Adds a box to the post editor that lists every custom field stored for the post, hidden ones included, with serialized arrays and JSON shown in a readable layout. Nothing can be changed from it.
Register Page Templates From a Folder Outside the Theme
Adds every PHP file in wp-content/page-templates/ to the page Template menu of classic themes, so custom layouts survive theme switches and updates.
Send PHP Values to the Browser Console
Adds a wpide_console() helper that prints any PHP variable to the browser's developer console for administrators, so you can inspect data without breaking the page layout.
