What things do you want to see in Survival Expansion v1.6?

I made a mod called Survival Expansion, and I released v1.5. I want to know what you want to see in version 1.6. Any suggestions for content in v1.6? It should not be any of the following:

Anything from another game or mod

Anything copyrighted

Anything that is not one of your ideas

Something not balanced for survival

It should be one of the following:

Any original ideas

Something balanced for survival

Something for a biome/dimension with biome having a low amount of mobs
