"QUICK VIEW" option is available on most shopping carts.. it could be a great addition to Viart cart.

what is quick view? it is not self explanatory as you might think...

when u can see product details in pop up window from products list page
http://quickview.mangoextensions.com/
there is a button "quick view" when mouse over item.

this is possible in the latest viart shop in the special products block as a popup on mouseover. should not be hard to implement to your preferred view type of products
