Perhaps the main use I have for the Aircraft (Beyond Atomic Bomb-ing big biter bases) is for exploring large swathes of map without having to clear out very biter nest I come across.
Thing is, between the great speed for most available aircrafts, and the minimap's small size, I'd be nice if there was some grid add-on for the planes to make their map-discovering area larger. That way we can make full use of the speed.
