Feature: Display Term Description on Hover

I liked the way Taxonomy DHTML popped the description up in a tool-tip when you hovered over a term, so I patched the code below to provide that functionality.

/**
 * Implementation of hook_menu().
 *
 * Most of the heavy lifting of the module is done here.
 */
function taxonomy_menu_menu($may_cache) {
  $items = array();

  if ($may_cache) {
   $items[]= array (
      'path' => 'admin/settings/taxonomy_menu',
      'title' => t('Taxonomy Menu settings'),
      'callback' => 'drupal_get_form',
      'callback arguments' => array('taxonomy_menu_admin_settings'),
      'access' => user_access('administer site configuration'),
      'description' => t('Global configuration of taxonomy menu functionality.'),
      'type' => MENU_NORMAL_ITEM,
    );

    $access = user_access('access content');

    foreach (taxonomy_get_vocabularies() as $vocabulary) {
      if (variable_get('taxonomy_menu_show_'. $vocabulary->vid, 1)) {
        $path = 'taxonomy_menu/'. $vocabulary->vid;
        $items[] = array('path' => $path, 'title' => t($vocabulary->name),
          'callback' => 'taxonomy_menu_page', 'access' => $access,
          'weight' => $vocabulary->weight, 'description' => t($vocabulary->description));

        $tree = taxonomy_get_tree($vocabulary->vid);
        $old_depth = -1;
        $old_path = $path;

        foreach ($tree as $term) {
          if ($term->depth <= $old_depth) {
            $slashes_to_remove = $old_depth - $term->depth + 1;
            for ($i = 0; $i < $slashes_to_remove; $i++) {
              $old_path = substr($old_path, 0, strrpos($old_path, '/'));
            }
          }
          $path = $old_path .'/'. $term->tid;
          $old_depth = $term->depth;
          $old_path = $path;
          $items[] = array('path' => $path, 'title' => t($term->name),
            'weight' => $term->weight, 'description' => t($term->description));
        }
      }
    }
  }

  return $items;
}
