I was originally going to try and make this mod myself, but after decompiling a few DLL files I have come to realize that I am way out of my league here.
What I'm asking for is a mod that, when the player character kills/knocks out an enemy, their inventory will be added either directly to the players inventory or added to the random loot obtained after the battle. This way it feels like you had first dibs on the loot from the guys you downed, without just flooding the after battle loot with ALL the high lvl gear.
