Knew Concepts review for Buy Button channel

It works great, but we've lost some customers because they have a pop-up window blocker, so they don't see the checkout window. It would be great if there were an option to not have the pop-up checkout, and direct the customer to the checkout in the same target window where our website is. Then, a "continue shopping" button in the checkout could basically be going back one in the history, to where they left off on our website. Or, give me the option where I would like them to go (our "shop" page showing all our categories).
