how to sort by DESC ? i'm was try a:
ImModel:etPref('gsortby', 'title');
but it's not working

how to sort by add date ex: by time added
i'm was try a sort menu by asc

PHP Code:

<?php
$manager = new ImController();
$preferences = imModel::getPref();

// Register your link template
$manager->tplRegister(array(
              'loop' => '<a title="Click to go to category..." 
                   href="[[ my_group_url ]]">[[ my_group_title ]]</a><br />'
));

foreach($preferences->categories->category as $cat)
{
    // setup items by category
    ImCategory::setCategory($cat);
    $manager->runModelMethod('gen_register', array('group_url', 'group_title'));
    $items = $manager->getModelValue('items_ordered_struct');
    // Render your link template
    echo   $manager->paint('loop', array(
                'my_group_url' => $items[0]['group_url'], 
                'my_group_title' => $items[0]['group_title']
    ));
}
?>

it's possible to add a number of items what have a category ? example:
category one (24 items)
