WordPress 3.1 added an “admin bar” that floats along the top of your blog when you are logged in with an account of sufficient privileges, giving you easy access to frequently-accessed pages in the WordPress admin.
It didn’t take long for plugin developers to start finding ways to extend it.
Weblog Tools Collection has a small roundup of admin bar plugins, which add additional functionality to the admin bar. One lets you manage what appears on the bar, and several add entirely new items such as debugging tools.
