Currently you can zoom in and out on the box art of the 3D model box using the scroll wheel on the mouse. The problem is, the zoom just zooms in to the centre of the box, irrespective of where the mouse cursor is when you are zooming in. Similar to with Google Maps, the user should be able to zoom in to a specific point on the box by the zoom going to where the mouse cursor is. On zoom out, the box should reset to the default location on the screen.
If you hold down the middle mouse button, you can pan around the 3D Box Model, allowing you to zoom in on a specific point, or move around the model after you zoom in.
