Hello,

I think it would be really helpful for players to be able to see how much space is left in a chest. This way, players can see how much of an item is available to buy and how much space there is, so that they can sell. While I personally suggest having a command that displays the amount of items in a chest that the player is pointing at, anyway that you add this idea would be helpful. Thank you.
