Oh! Well, you need a way to link to the page with the impact tab open, since I never noticed there were tabs at all! It's still very unclear that the left quadrant is a mini-map of the other three quadrants. I recommend just graying out the top left and writing "Zone 1 - High Impact" somewhere inside the quadrant it describes.
