Plugin missing shopping_url option

This plugin is ALMOST perfect for what we needed. The only thing it was missing was to allow us to specify the shopping_url hidden input option so that if a shopper added something to their cart and then clicked “continue shopping” it would take them back to our desired shopping page instead of the websites homepage.

I had to manually input the whole PayPal <form>..</form> instead of using this plugin.

Another take would be to allow custom hidden input items. That would allow for shopping_url or any other needed content to be sent in the form to PayPal.
