This plugin allows the website administrator to remove the following from the WordPress Administration Panel:
<ul>
<li>menu links (like “Tools”, “Appearance”, or annoying menus from third-party plugin)</li>
<li>submenu links (like “Users > Your Profile”, “Tools > Available Tools”, or annoying menus from third-party plugins)</li>
<li>and dashboard meta boxes (like “QuickPress”, “Other WordPress News”, or annoying meta boxes from third-party plugins)</li>
</ul>
It relies on hardcoded settings in wp-config.php (instead of having yet another admin settings page to deal with). Since the settings are all hardcoded, it can be easily set up by a website administrator and left in place without any users messing with it. It works on both single and multisite installations.
