When first playing, I was a huge fan of the blue/purple aura around rarer drops. Also, when getting ore drops with ore discovery there is a brief blue flash of light, although the item doesn't glow. I love this, as it gives that slight bit of hype when something drops.
However, when I started using @autoloot the items no longer drop on the ground. This causes no noise/light flash/glow of any sort. It would be a great update to make a blue/purple color flash appear on an enemy during it's death animation if it dropped something rare, even if autoloot is on.
I don't know the codebase so this might be a nightmare to implement, but would be fantastic if it's easy to implement. Visuals for getting that low odds item always feels good.
