Enable Hidden Administration Feature displaying All Site Settings

Tested on: WordPress 3.1 RC3

This little piece of code does something pretty cool. It will add an additional option to your settings menu with a link to “all settings” which will show you a complete list of all the settings you have within your database related to your WordPress site. The code below will only made this link visible to an administrator user and hide it for all other users.

// CUSTOM ADMIN MENU LINK FOR ALL SETTINGS
   function all_settings_link() {
    add_options_page(__('All Settings'), __('All Settings'), 'administrator', 'options.php');
   }
   add_action('admin_menu', 'all_settings_link');
