This is just a small suggestion for the servers with crates. Mineverse should make it so when you left click a crate, it shows you what you can receive from it. And when you right click you use your key. This will make it so players know what to expect. Also it will tell the chance of getting the item.
This brings up new things. Why not revise and add stuff to crates. (After we see what we can get of course!)
