I think there should be some new furniture.
Couches, Chairs, Tables, etc.
I mean sure, Piston tables look nice, but I need something that looks better.
I also think that Horse Armor should be craft-able in some way.
I think there should also be some sort of new dimension, similar to the Aether, but obviously not the same..
I think a new ore that is stronger than diamond would be cool as well.
