Not sure if this is possible, but a smart coordinate scroll would be useful for quickly checking surface elevation.
Currently, the coordinate scroll only gives you one surface elevation at a time but I wish it would show two or more surface elevations and the delta between the surfaces. This would be useful for checking sub grade to finished design
Additionally I with you could apply formulas so that it automatically adds or subtracts from the surface elevation. This would be useful for checking architectural plan elevations that are usually given in relation to a 0.0 base elevation.
