In the case of chest etc I do not care only for empty containers but (as the legendary Harvest Containers mod for oblivion did) FOR ALL THE containers I (the player) open - cause most of the time I do not empty them but I want to have a visual indication that I opened them. The empty ones (those that are empty to begin with) might as well have the same mesh as those that I opened - two birds with one nif
In short Harvest containers sorely missed
