I feel like this has already been suggested, because I find it hard to believe that no-one else has wanted this, but could we include something to keep track of a units vission range? Perhaps attach it to your equiped weapons tooltip? So you would have your range, then vision. Either that or you could use the stats slots for the normal strength, intel, agility, etc. on the right side of the units information... thingy (like what was suggested for the shield armor).
