Have you made the mistake of putting a access sign on the side of a chest? Well I think that should be a thing it would make it easyer to access things in bulk so we can have chests ontop of each other. Prob going to benchmarked till 1.13 And is there a date for releasing it?
I'm to lazy to look but there is another suggestion like this and Chickeneer has even commented on it. I suggest scouring through the suggestion archives.
