For some stores, the default configuration of shipping options may not be enough. Say you have frozen items, and you only want to show one set of rates if those items are in the cart and hide them the rest of the time? Shopp doesn’t natively support this configuration. With Shopp Category Shipping Filters, you can configure each product category that applies to each shipping method.

Warning!
Visa and MasterCard rules require that merchants only authorize payments for delayed fulfillment orders 
until the order ships out. In other words, merchants are not supposed to capture the payment until the 
shipment is handed over to the shipping carrier. It is not illegal to authorize and capture payments 
before shipping. But it puts both the merchant and the customer at higher risk. 
For this reason, to protect the merchant, Shopp uses authorization-only payment processing for shipped orders.
Despite the risks, some merchants still prefer the automatic capture when new orders are placed. 
You can edit your theme’s functions.php but these changes are easily lost when you change your theme. 
This plug-in will do the dirty work for you.
