Just create a plugin using forumdisplay_complete with the following:
PHP Code:
$newTemplate = vB_Template::create('navbar_breadcrumbs');
$newTemplate->register('navbits', $navbits);
$breadcrumbs = $newTemplate->render();
$breadcrumbs = str_replace("'", "'", $breadcrumbs);
// to put it above the Forum Information box
$find = '<div id="forum_info_options" class="forum_info">';
$vbulletin->templatecache['FORUMDISPLAY'] = str_replace($find,$breadcrumbs.$find, $vbulletin->templatecache['FORUMDISPLAY']);
That should do it. I'll put it in my next version.
