Looks great - looking forward to seeing the pro version. One fix for bugs.php:
Code:
if ($vbulletin->GPC['vbug_versionid'])
{
$condition .= " AND vbug.vbug_versionid = " . $vbulletin->GPC['vbug_versionid'] . "";
}
Also notice an empty <span> tag in list template that is unecessary.
Probably not a bug, but seems if you edit a ticket, it assigns it to the first person in the dropdown, not leaving you the chance to leave it unassigned.
