The quadrants below the radar are not easily distinguishable

There is no separator (either a line, or more spacing) between the quadrants list. So "HOLD" from the left quadrant is as close to "ADOPT" from the other quadrant, as it is from the "ASSESS" from its own quadrant.

In the latest version, this is solved by using borders and more spacing between the quadrants
