You can add your favorite icon simply uploading it in the right directory of your joomla-website.
You can have only-icons menu with useful tooltips! Or mixed menues with icons and titles... Amazing!
Also this module is ok for every browser (firefox, opera, safari, ie8, chrome, etc...) - I tried it!
Support is superb! But the module is so-that simple to use that every buddy webmaster like me can install and enjoy it.
Good work, Ninjaforge!
