Hitech,
It would save time from having to run builds, go offline, then check your plane icon direction at each end of the gun arch on the CBM. If the shore battery had a setting to show in red the angle of it's sweep arc with each ray end out to max range for the 8inch, this would help in setting down multiple batteries. On an aside, a ring for the new AA feilds showing the maximum activation range diameter would help in placing them down. Unless that is a number I don't know of, which I could put into the circle setup to check it that way.
