Other info

I'm going to add more features to this mod later, now I just ran out of ideas.
Now, UtilsMod is available for only two versions of the game (1.21.4 and 1.21.5), in the future, perhaps the mod will be released for older versions, like 1.20.1.
I have not completed the development of this mod to the end, one of the consequences of this is that now it has ARR license.
I really hope you enjoy this mod!
