Jim,
Thanks for the great feedback. We do have that on our Wish-List and I just made a recommendation to make the Towers larger and possible even shade in the red circle. I'd even love to see only the Tower in concern be shaded, example if there is a tower 3 miles behind you, do you really need to see it called out. Maybe we show it if within a set altitude and then only highlight it if it is near your track or flight path. Just some thoughts. Stay tuned, this will likely be added in the near future.
