Adds a "Site extras" section to Appearance > Customize with a footer note and a contact phone field that preview live, and makes them available with a [site_extra] shortcode, as a pattern for your own settings.
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.
Turns on featured image (post thumbnail) support for themes that do not declare it.
Stops PHP deprecation notices coming from plugins and themes from filling debug.log, so the real warnings and errors you are looking for stand out while debugging.
Adds a Tools > Shortcodes screen listing every shortcode available on the site and the plugin, theme or function that provides it, so you know what can be used in content.
Enqueues custom.css from the active (child) theme folder if it exists, with a version based on its modification time to bust caches.
Writes every deprecated function, argument, hook or "doing it wrong" notice to the PHP error log with the plugin or theme file that caused it, even when WP_DEBUG is off.
Wraps every rendered block in HTML comments with its name, such as core/group or a plugin's block, when an administrator views a page with ?wpide_blocks=1, to see which block produced which markup.
Adds a public /wp-json/site/v1/menu/{location} endpoint that returns the menu assigned to a theme location as a nested list, ready for a headless or app front end.
Adds new menu locations, such as a footer menu and a legal links menu, that you can assign under Appearance > Menus and print with wp_nav_menu() in a classic 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.
Adds a Tools > Image Sizes screen listing every image size WordPress creates on upload, with its width, height and crop mode, so you can see what themes and plugins have added.
Stops chosen plugin or theme scripts and stylesheets from loading on the front end, optionally everywhere except the pages where they are needed.
Counts the external HTTP requests WordPress, plugins and themes make while building a page, and lists each URL, status and time in an admin bar menu for administrators.
Shows which Git branch and commit the site or theme is running in the admin bar for administrators, so developers always know what code is deployed on each copy.
Displays the theme template file (and block template, on block themes) used for the current page in the admin bar, for administrators only.
Adds a "Template parts" menu to the front-end admin bar for administrators listing every template part loaded on the page, for both classic themes (get_template_part) and block themes.
Adds a "Subtitle" box to the post editor, saves it securely and provides a [wpide_subtitle] shortcode and a helper to display it in your theme.
