Sex up the UI with form #states

I've form-altered the menu icons UI to hide the unnecessary form fields until the check box is checked. Thought you might be interested in this as well:

    // Make the 'path to image' and 'upload image' fields hidden until the checkbox is checked.
    $form['icon']['icon_path']['#states'] = array(
      'visible' => array (
        ':input[name="use_icon_logo"]' => array('checked' => TRUE),
      ),
    );
    $form['icon']['icon_upload']['#states'] = array(
      'visible' => array (
        ':input[name="use_icon_logo"]' => array('checked' => TRUE),
      ),
    );
