I couldn't find a mod like this, so I figured I would suggest this idea, as I believe many would want it.
It would be a mod that you can configure or enable through separate esp files that would automatically pick up money and/or alchemical ingredients from slain enemies, either by your own hand, your partner's, or other allies around.
This would then remove the time required to stop at each body and manually grab money and ingredients when this is all one cares about. Already having decent weapons, armor and other items, I think this would definitely help keep the pace moving quicker to each side quest, dungeon, ruin, etc.
Let me know what you think.
