Anything in particular you hope to see in 1.4 that hasn't been spoiled?

I'm personally hoping for more thrown weapons, just to give ranger more variety, that and an official boss for the snow or desert biome.

I myself really just want the ability to see a preview of the world as it generates, similar to jopojelly's WorldGen Previewer mod, perhaps maybe with elements of the Terraria Seed Project mod integrated into it, namely since it drives my OCD nuts to see the world evil infecting and destroying part(s) of the jungle and to possibly search up seeds in-game without having to rely on a modded version of it.
