WordPress 3.1 introduced the admin bar, which adds admin options to the top of your pages as you browse your site (Assuming you’re logged in of course).
It’s easy to extend the bar to add new links of your own, or to remove links you don’t want (e.g. if the “Appearance” menu isn’t something you often need instant access to).
In this tutorial, we’ll be building a simple plugin that will let us add some handy links (e.g. a Twitter search for the current post, analytics, and ad sales), as well as remove the links we don’t want.
