The Utilities Function Pack is designed to help users out by simplifying complex command creations into just one function that the user can call and execute so that they don't have to do any complex command block creations on their world.
The Utilities Function Pack has many uses, and this first release is geared towards realm owners, but still has a few commands for Creative enthusiasts to use.
That will give you the tag Admin making you essentially an Admin. In the next update, this will be fixed and you won't have to worry about it though. Also in the next update, I will probably be re-uploading this as a new submission, named "Realm Protection Plus", to better reflect what it is for.
The only thing that may occur is a slight lag with the World Edit, because of everything it will be doing. But the techniques I will be using should not cause anybody to lag, I focus very heavily on that part.
Anyways, looks good!
