QuickEdit without Toolbar

I only wanted QE to show for admin users. Changing output.class.inc.php does the trick for me:

if ($modx->isMemberOfWebGroup(array(’admins’)))
{
$html_top =<<<EOD

<!-- Start QuickEdit toolbar -->
<div id="QE_Toolbar">
<h1>{$QE_lang[’QE_title’]}</h1>
<ul>
{$menus_html}
</ul>
</div>
<!-- End QuickEdit toolbar -->

EOD;
}
else
{
$html_top =<<<EOD


EOD;
}

This will result in some JS errors in QuickEdit.js--for every JavaScript error I just put an "if(this.toolbar)" (or whatever it was erroring on) before the faulting line.
