If any of you have seen @mikelaurence
live twitch stream, you can see that he has a ton of commands we don't get! Boo hoo. But there's one command that admins get that I really like, no not the "God" command, but the "count" command. Let me tell you how it works.
You type /count ground/diamond and it shows you how much diamond is in your world that is in the dirt somewhere.
I find that this command should be for world owners and world members (or selected players that the world owner chooses).
Again this is just an idea, I am not saying it's going to happen. If any of you wonder, I chose "I would like this command".
