no limit fill

Hi guys, this is my first mod, so don’t judge me harshly.
This mod allows you to do almost everything the same as in the World edit mod only without a hatchet.
this is the fill command, but without restrictions, if you register in the chat without sending /u, then all the commands of my mod will pop up to you. I do not know how several commands work, but try them and you will understand everything. I am writing this text through a translator because I do not know English well. press the right alt button again (you can change it to any other button in the control settings), and you will see several functions. One of them does not work is a quick dig, but I will fix it. I hope you all enjoy my mod so far.
