So far I've made 4 datapacks, and I already want to make one. Unfortunately, I'm out of ideas currently. So I need your ideas. These are the guidelines for the suggestions.

-Datapack must change/add atleast 4 features.
-Be original and must not be repetitive.
-PG-13
-Must have a purpose.

So, comment down your ideas, and they may be in a datapack!
