Control and Customize the WordPress Toolbar - change/enhance the colors and styles, hide menus and buttons, change the text next to your username.
Recently updated for WordPress 3.6 and more in sync with the default WordPress toolbar behavior than the last version.
Using the paid version, for 20USD I don't find it yet worth the price.
