I was still longing for a mod for Floating Damage Numbers...
Whenever one of your units in the battlescape takes a hit, a number briefly floats from their center to slightly above them indicating the damage taken (the damage is 0 if fully absorbed by armor). In case of explosions, at the end of the explosion, the damage numbers simultaneously float over the affected units. Damage numbers don't appear from fatal wounds, just direct attacks.
Damage numbers do not appear from enemy units unless they are under your mind control. That's the whole point of "enemy unknown". Damage numbers also do not appear from civilians either.
I would like to see 2 versions of this, one for UFO Defense and one for Terror From the Deep.
