I feel that while the ruler can be very useful I don't think its useful enough yet. I feel this way because you can only measure as far as your screen extends which can be a bit of a pain in some instances. So what I was thinking is that if you have the ruler enabled and you open the big map the ruler will work on the map for just that case that you may need to measure out an area larger than your screen. Now this could either be part of the ruler normally or you could maybe combine it with the mechanical ruler and a map to make one that works on the big map.
