Ozh has developed a very neat plugin for wordpress which converts the wordpress administration menu into a very neat and tidy drop down menu based system which makes the entire administration section much better!!!

You can find the plugin which goes by the name Admin Drop Down Menu here

In the last update there are now not only cool icons in the drop down menu but Ozh has also provided a Plugin API for other wordpress plugin developers to be able to do very neat things!

One of them for example is, being able to associate a custom icon for their own plugin options page link in the administration menu! Using the following sample code, plugin developers can now very easily add custom icons:

// Add a page like usual
add_options_page('My Plugin Settings', 'My Plugin', 10, 'myplugin', 'myplugin_do_admin_page');
 
// Add a cool icon
add_filter('ozh_adminmenu_icon', 'myplugin_icon');
function myplugin_icon($hook) {
          if ($hook == 'myplugin') return 'http://path/to/icon.png';
          return $hook;
}

Apart from this there are several other neat hooks available as well that WordPress plugin developers can make use of and achieve nice things!
