2 minecraft command and edit 1 command idea

you know when you trying to move a building in minecraft with only two commands: clone and fill

you use fill to remove the building and use clone to clone it in another place so What if we mixed them

/clone + /fill = /move

its better and useful

command: /move [first xyz] [secound xyz] [to]

and a new command in minecraft will make it better

the command is /size

useful to make map devs make you small or big maps and to size other mobs to make them like giant

command for players: /size [username] [size]

command for mobs: /size [entity name] [x] [y] [z] [size]

[size] is 1 to 50. less is smaller and more is bigger. default is 10

so i want too to make the /clone command better

new command edit: /clone [username] [x] [y] [z]
