Eagle Eye Rangefinder Upgrade
The Eagle Eye ability should have an upgrade that expands the aim markers, and when aiming at a specific target (such as a beehive, enemy infrastructure, or an actual enemy) tells you exactly how many metres of distance your shot is. This should also not have a range LIMITATION, by which I mean, if I can see the thing with Eagle Eye well enough to see it moving and try to aim at it, the marker should tell me how far away it is - and put the number in red if there is no arc which would result in a hit from my current location.
This could even be two separate upgrades for the same power to add levels of investment to it.
