chest that are linked

if you put something in one chest then it would also be in the other and when you take it out it will be gone like an end chest, but anyone can get the items

This would be super helpful if you can't get back home, but you don't want to lose your stuff, but the chest is already filled up you can have a friend get the stuff out of the chest and you could fill it up again then die and you won't lose your stuff
