This mod will make empty chests and barrels gradually fade out after they are opened, becoming darker and partially transparent.
This mod is intended to be an alternative to EmptyChestsBeGone, which simply deletes opened containers. I made this because I wanted to be able to still see where containers have been. If you don't care about that, consider using EmptyChestsBeGone instead—it's simpler and probably less prone to weird stuff happening :p
Tested and works in multiplayer! (Well, mostly; see Known Issues on GitHub.)
