It would be good if you could add a box to define the border-radius for the class .hikashop_subcontainer which nou is fixed to 5px inside the module.php
Code:
#'.$main_div_name.' .hikashop_subcontainer {
-moz-border-radius: 5px;
-webkit-border-radius: 5px;
-khtml-border-radius: 5px;
border-radius: 5px;
although is a minor change it prevents from "hacking" core code and thus losing control after upgrades.
Thank you.
