It would be really nice of you could change the difficulty of your single player game when you use it for multiplayer, I started on medium difficulty and would like to make it harder when I have people playing with me, also being able to switch to creative mode would be really nice when building mega structures
It would be nice to see the ability to jump between creative and the other difficulty modes in game whenever you wanted, I have a few files going and we want to create a giant structure in creative then switch to hard and gather and collect to build everything else. I get some people might think it ruins the game but sometimes It's nice to make a huge structure without needing to spend days gathering grass/weeds
