Sorry i don't use it but I know of it... the dot command that highlights a selected target....
Just watching a vid I noticed what could be a bug.. and probably not a great thing unless you use it as an exploit.... but the box around the target distance does not disappear when everything else does while flying through clouds... so the possible use of clouds to evade and turn the tables enemy is not possible as you can see where the con is even if you can't see the plane or its distance.
