"Recently Edited" Menu in the Admin Bar
Adds a menu to the admin bar listing the last eight posts and pages you edited, with their status, so you can jump back into your work from anywhere on the site.
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.
Bookmark Admin Screens in the Admin Bar
Adds a star menu to the admin bar where each user can bookmark the admin screen they are on, such as a plugin's settings or a filtered list, and jump back to it from anywhere.
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.
