How do I change the order of objects (i.e. move some to the foreground and others to the background

Why does the software not provide an order functionality. I.e. it seems all objects are on the same plane, but they aren't. For example, if I have a few objects and then place a rectangle box around them, the box is now on top. So if I want to click on the objects within that rectangle (which appear beneath the box), I have to first move the box out of the way, then move my objects and then move the box back. This is silly. You should be able to just send the box to the background so I can touch and select the objects inside the rectangle box area.
