I've noticed that there's a 'tail' sometimes extending from the center crosshair a varying distance. I'm assuming this is some kind of indicator, but I'm unable to determine what it indicates. Have you guys noticed this, too?

That indicator shows you the difference in height between the place you are standing and the place you are aiming the cursor... the arrow wont show if its level or same height.

I thought that's probably what it was. What wasn't apparent was that the tool will level to the spot you're standing on, so the tail will either raise or lower depending on your height differential to the area being leveled. I'd really like to see a little more thought put into the way this tool behaves and displays.
