Howdy Danielle,
There are plans to modify the cart page to an extent. Primarily we are interested in giving people the ability to edit their attendee info right from the cart. That will be an upcoming feature released as part of Event Tickets Plus. I am not certain how it will look just yet. The cart page of Woo purposefully has less info than the other pages, and so the full order details might be inside of a link we add to that page, a popup, or some other format that does not conflict with Woo.
I am very happy to hear you got that working Chloe! This extension is a newer version of the one you mentioned, so you would not want to run both simultaneously.
Thanks for the feedback guys!
