/deletemap <txt><devpass> <tries>

When this command is ran via command block the screen with fade out to black and then text saying the raw txt with 2 buttons

Delete

The delete button deletes it. (obviously)

Password

This will let you enter the password, if you fail <tries> times it will go back to the main screen with the button locked

Execptions:

It will not be allowed if it is via player and it also won't be allowed to be ran on multiplayer (excluding LAN) 

It also won't run if you dont specify the pass, chances, or you have below 1 chances inputted

Example:

/deletemap ["",{"text":"This is an example","bold":true}] "1234567890" 1 would give this:

(It's a rough sketch thing I made in MS Paint)

Anyways that's my idea. (Bye)
