Once a customer has entered the checkout flow, there's no easy way for them to get back without using browser back buttons. What if they landed in the checkout flow but aren't quite ready to commit yet? simplest solution would be for our store logo to link back to our homepage - store logo is showing in top left of checkout but is NOT a link. Can we add something so the customer can return to store, or a "continue shopping" button BEFORE they reach the thank you page of the checkout flow?
