Drop "Uncategorized" When Another Category Is Chosen
Removes the default category from a post as soon as it has another category, so posts do not end up filed under both.
Snippet Library
Admin snippets for WordPress
Snippets that tidy up and tailor the WordPress admin: hide menu items, add columns to post lists, change the footer text and remove clutter. Made for agencies and site owners who hand a dashboard over to clients or editors.
Filter Posts by Author in the Admin List
Adds an author dropdown next to the date and category filters, so editors can list one writer's posts.
ID Column on Category and Tag Screens
Adds a sortable ID column to categories, tags and every other taxonomy screen, handy for shortcodes and filters that need term IDs.
Keep Checked Categories in Their Place
Stops the classic editor from moving ticked categories to the top of the list, so the category tree keeps its order.
Limit Posts to a Single Category
Keeps every post in exactly one category: when several are ticked, only the most specific one is kept on save, which keeps URLs, breadcrumbs and archives tidy.
Prevent Deleting Categories That Still Have Posts
Stops anyone from deleting a category or tag while posts still use it, which avoids accidentally emptying sections of the site or breaking menus and links.
Remember Your Filters in Admin Lists
Brings back the status, category, author, search and sorting you last used when you return to the Posts, Pages or Media list, instead of starting from "All" every time.
