When WordPress 3.1 premiered, the new admin bar was probably the most noticeable new feature. Hiding it is as simple as unchecking an option at Users -> Your Profile in your Dashboard, but what if you’ve embraced the admin bar and actually want to add to it?
As you may have expected, there’s already a healthy handful of plugins that add functionality to the admin bar.
Admin Bar ID Menu displays the ID number of the page, post, category, or tag you are looking at in the WordPress Admin Bar.
Debug Bar adds a debug menu to the admin bar that shows query, cache, and other helpful debugging information. When WP_DEBUG is enabled, it also tracks PHP Warnings and Notices to make them easier to find. When SAVEQUERIES is enabled, the mysql queries are tracked and displayed.
Debug Bar Console adds a PHP/MySQL console to the debug bar. (requires the Debug Bar plugin)
Debug Bar Extender adds more features to the debug bar and is mainly aimed at developers who like to debug their code or want to measure runtimes to find glitches in their code. It also allows lookup of variables by adding simple code snippets in your source. (requires the Debug Bar plugin)
Logged Out Admin Bar makes that admin bar always visible even for logged out users. Adds a login button when logged out, the shortlink also displays when available.
Snack Bar adds a snack menu to the admin bar that provides quick access to blog/network admin screens for SuperAdmins.
WordPress.com Stats add a 48-hour stats chart for each page to the admin bar.
WP Custom Admin Bar gives you options to change who sees the Admin Bar based on their user role, change or override the default styling, and remove the Admin Bar altogether.
What do you think of the new admin bar? Are you using a plugin that we’ve missed? If so, we’d love to hear about it!
