Sort by Stock

Hi,

This is a nice feature. Thanks for the suggestion.
However, it is not possible with current version but I would definitely try to add this in future release.

For now you can add this code in theme functions.php and let me know if this works.

/**
 * Order products by stock status.
 * 
 * @param array $args 
 * @return array $args 
 */
function wpes_support_16872473($args) {
    if (function_exists('WPES') && is_search() && empty($_GET['orderby'])) {
        $args = [
            'meta_key'  => '_stock_status',
            'orderby'   => [
                'meta_value' => 'ASC',
                'date' => 'DESC'
            ],
            'order' => 'DESC'
        ];
    }

    return $args;
}
add_filter('woocommerce_get_catalog_ordering_args', 'wpes_support_16872473');

Thanks
