Maybe an in-game (accessable from the furniture tool) or LORE list on all the people who has opened (and when they last opened) a persistent chest?
Might help when figuring out if one loses all items in a chest due to theft (i.e. post a thread in griv forum) or due to stuckiness-bug (might not result in a thread in the griv forum, if the items aren't very, very important).
Would also be nice if the chest owner could clear the log.
