There is only one caveat. You can see both the ranges of your own units, but also that of the enemy. This largely negates fog of war of the enemy air units. By setting your cursor on an enemy air unit and looking at the range circles it is quite easy to deduct what type of aircraft it is. Still a great feature.
But I have to ask, would it be possible to also choose between showing ALL range circles of the air units, or just the range circle of a specific air unit? In areas with lots of air units present, there can be a LOT of circles you know
