Abandoned cart analytics and testimonies

I would love to see a way to have the name and email entered then payment. If this would be possible without having to use the custom page feature that would be a bonus. (I have a landing page on my Wordpress site.)

Maybe something similar to Thrivecart.

I would also like the ability to add a few testimonies and maybe a picture of what they get on the checkout page. (This may need to include a custom page.)
