Man Admin

Aaron Butacov

This plugin allows you to add whatever you want to the WordPress dashboard through PHP and HTML even Sidebar Widgets. You can also wipe the entire dashboard or individually remove some of the more irritating sections like the Dev news, Planet WordPress and the getting started section.
In WordPress 2.5, the code is cleaner, the plugin is more responsive and you can add both “real” sidebar widgets, or add “fake” ones to match the dashboard.

Dashboard Editor

With this plugin you can remove sections of the dashboard, add new code, or even add Sidebar Widgets.
