I am in the process of building a new website. I am looking for a Guest checkout.

I have used Fast and easy checkout in the past and it does work as advertised.

I noticed this plugin one-page checkout includes a guest checkout.
Though it seems as if there are way too many steps in the process. I never seen a checkout page that has “save” to go to the next step. In my opinion customer will abandon the cart if they have to press save on each step. Is there an alternative plugin that can do guest checkout the correct way without having to save to go to the next step.
