The cart/product page need the qty field editable. Currently on a page, once you add to cart it disappears... either it should stay. or should have a rollover showing "item added" then switch back to add to cart again
When item in the cart, you can't edit the qty, so what's the point of a update cart button?
Also the "Remove item" does not properly work... it currently removes 1 qty, needs to remove entire item regardless of qty... I added 1000 for test and you could see the problem id have trying to remove it...
an ajax cart with a "+", "-", "Remove" options to make adjustments and remove the update cart would be perfect
