Would be nice to have, but then wouldn't it cause whines about the clouds making it impossible to see?
Just go no icons. Then it would be the aircraft itself disappearing behind the clouds. Also Its hard to pick if you have to make sure of aircraft identification prior to engaging. Of course there would be complaints because so many would probably be shooting down them selfs with kill shooter on.
Fly a spit. U will blend then shoot at the nearest spit and yell that somebody behind u is shooting. Do again couple of mnutes later.Semp
Then just have it in FSO's.
