Command Wand or Macro

A command wand we can fill with a command in a command block-like menu that open when sneak+right click and that execute the command when we right-click.

Or macros, that are commands we can bind to a key.

Useful for:
-Building faster with fill, clone and in-air setblock commands.
-Command like /time set day, /tp FriendsName and other commands we need to re-write a lot of time.
-For building faster.
-Adventure map with custom item (by combining it with CustomModel nbt)
-And above all, for building faster.
