Currently, visual feedback regarding damage on others is...well, non-existent really. Besides the hitmarkers and potential loss of armor I suppose.
So I would suggest a relatively simple feature: The good ol bloody effect over people, scaling with damage received (probably better known from games like Mordhau or Chivalry). Someone close slightly hurt would have a few blood splatters over their face and uniform, someone close to death would have quite some blood all over them, ideally someone who is actually downed would have noticeably more blood over them.
This would fix two things.
For one, you'd simply get some decent visual feedback as to how much you actually damaged your enemy.
For another, we actually could reliably tell downed people from people lying prone apart (huge issues at times, especially when the campers cluster up, but it's generally confusing and makes you shoot when in doubt...or worse, not shoot when you should).
I'd say the damage effect itself is optional, especially since it would soften the visual gap and make the feature less impactful on downed targets. But some actual visual difference for downed people would be a huge QoL improvement.
If this is not done for performance reasons, that's fair. Whatever is needed to make this run on a Nokia 3310.
