function views_ui_get_form_progress($view) {
  $progress = FALSE;
  if (!empty($view->stack)) {
    $stack = $view->stack;
    // The forms on the stack have integer keys that don't change as the forms
    // are completed, so we can see which ones are still left.
    $keys = array_keys($view->stack);
    // Add 1 to the array keys for the benefit of humans, who start counting
    // from 1 and not 0.
