I noticed that the Track Your Order button is shortened. If I set my theme Layout to be Big Preview with no Sidebar, it does increas in size, but not quite full yet.
Also, if you add something to the cart, the image doesn't seem to show full. However, when you first add something to the cart, the cart on the top menu shows the full image when you hover over the cart icon.
Not a real issue, but I think it used to show a full picture (mybe it's some plugin causing this?).
