Awesome Plugin

Thanks for the plugin! I want to suggest a change to the plugin. Before I have issues related with the change of statuses and emails:

If I change the status from: Waiting to Pending -> The email is sent
If I change the status from: On-hold to Pending -> The email is not sent
(I do this cause sometimes I have to modify the orders, and for that you need to be on “On-hold” status).

So, to solve this I added this line of code (182) to the class-sg-order-approval-woocommerce-pro.php file:

$this->loader->add_action( 'woocommerce_order_status_on-hold_to_pending',$plugin_admin, 'oawoo_status_waiting_approved_notification', 100, 2 );

Maybe will be good to dispatch the emails always when you change to waiting status, and also to modify the Pay now text and style (without modifying the code).

Again, thanks for the plugin!
