Only show vocabulary assigned to selected content-type

Actually, all vocabularies are shown in the first drop down list. Should be better to see only those assigned to selected content-types in the admin section.

To do this, in linktocontent_node.module, in the _linktocontent_node_get_categories function, replace :

  foreach ($containers as $item) {
    $obj = new StdClass;
    $obj->vid = $item->vid;
    $obj->tid = ($top ? $item->vid : $item->tid);
    $obj->title = (trim($item->name));
    $results[] = $obj;
 } // end foreach
return $results;

by

  $status = variable_get('linktocontent_node_content_types', array());
  foreach ($containers as $item) {
    $obj = new StdClass;
	if (isVocabularyForContainer($item->nodes,$status)) {
		$obj->vid = $item->vid;
		$obj->tid = ($top ? $item->vid : $item->tid);
		$obj->title = (trim($item->name));
		$results[] = $obj;
	}
  } // end foreach
  return $results;

and add the function as below :

function isVocabularyForContainer($container, $vocabularies) {
	$nopresent = array_diff($vocabularies, $container);
	return (! (count($nopresent) == count($vocabularies)));
}

Is this feature could be include in the next patch ?
