Cursor Traveler: mouse move counter

Your mouse cursor does a pretty good amount of moving. It darts from buttons to text boxes to links, always sending you to the next thing you want to look at. Those movements are all pretty small – only a couple centimeters across the front of your monitor… and yet one could easily see them adding up to pretty good distances over time. So, how far does a mouse cursor travel? Source of extension: https://github.com/dmfilipenko/cursor-traveler
