Very nice, some nits though: A slightly bug-ish thing with the zoom. One can continue zooming (moving the "focus point"?) even after it visibly stops zooming due to collision, making for a sorta confusing experience. Both right-click and middle-click behaves like left-click when over an item, is this intentional? Items can be hovered & selected through walls and moved the same way but there's no visual indication in regards to what's happening. There should be something like the red "can't move", except white or a transparent "item", visible through walls in these cases.
