Either add your code below:
Or you can make a plugin that will use the following template hook location.
Code:
{vb:raw template_hook.navbar_end}
Make a new plugin and add something like this. Set the hook location to global_start.
Code:
$templater = vB_Template::create('ARP_template');
$template_hook['navbar_end'] .= $templater->render();
See attached screen shot. I do believe this will work.
