Enhances the final checkout button by allowing only a single click to proceed to the invoice page. This feature helps eliminate duplicate orders and other storefront problems related to multiple clicks while the customer is waiting for the invoice/order to finish processing. The final checkout button can also be customized independently of the other checkout/continue buttons with your own text/image button featured in the module configuration. This feature clearly prompts the storefront customer they are ready to complete the checkout process and submit their order. Backwards compatible with browsers with JavaScript disabled where the final checkout button functions normally.
