Thanks. I've added the below to the main.php file in my theme and it works nicely...
Code:
protected static function moveClassesInLists()
{
return array(
'XLite\Module\Client\ClientTwitterFeed\View\ClientTwitterFeed' => array(
array('sidebar.single', 'customer'),
array('sidebar.single', 500, 'customer'),
),
'XLite\Module\XC\News\View\TopNewsSideBar' => array(
array('sidebar.single', 'customer'),
array('sidebar.single', 1000, 'customer'),
),
'XLite\Module\QSL\WordPress\View\Plugins\RecentPosts\MenuSection' => array(
array('sidebar.single', 'customer'),
array('sidebar.single', 2000, 'customer'),
),
);
}
