Without mousing over every aircraft, there is no way to know the altitude and collision potential or risk. TCAS and other manned aviation systems always have number floating with every object, and that number has a 2-digit +/- value in hundreds of feet that reports position. Displaying the altitude would be the second most-important piece of information after position. Since position is adequately handled, altitude should be displayed next.
