This plugin will hide the WooCommerce “Update Cart” button and reload the quantity changes dynamic over jQuery. You don’t need this extra click anymore!
This Plugin is based on a posting on StackExchange related to WordPress developers. I modified the basic concept and created a plugin out of it that WordPress users with less experience in PHP can integrate this function easily without destroying their functions.php file.
There are no options. Just activate the plugin and it will works.
