HotbarPriorityChanger
A mod that can change your hotbar slot's priority
About this Mod
This mod is made for you to be able to do the things Marlowww said in the video How Your Hotbar Order Impacts Minecraft PVP without reordering your entire hotbar.
If you want to have your axe in a bigger priority slot, than your sword but your axe is in the slot 1, and your sword is in slot 9, you can simply do it by typing /changehotbarpriority 2,3,4,5,6,7,8,9,1
So in /changehotbarpriority the later your slot's number is the bigger priority it gets.
Theese numbers are not your hotkeys
