Export quicktabs to code

I have been struggeling with this issue.

In admin/structure/quicktabs/manage/most_visited_topics/export I tried to export my quicktabs following the help text "Place this code in your module's implementation of hook_quicktabs_default_quicktabs() to provide it as a default quicktab."

So this is what I did

/**
 * Implements hook_quicktabs_default_quicktabs().
 */
function mymodule_quicktabs_default_quicktabs() {
  $items = array();
  ...// the exported quicktabs
  return $items;
}

But the quicktab did not appear. Finally I discovered this post.

So I also implemented

/**
 * Implements hook_ctools_plugin_api().
 */
function mymodule_ctools_plugin_api($module, $api) {
  if ($module == 'quicktabs' && $api == 'quicktabs') {
    return array(
      'version' => '1',
      'path' => drupal_get_path('module', 'mymodule') . '/exports'
    );
  }
}

This solved my problem.

So please extend the help text to refer also to hook_ctools_plugin_api() - or refer to http://drupal.org/node/1371626#comment-5372432
