HD textures for the remaining vanilla items
Small changes concerning balance, gameplay, or graphics.
Not sure if you can do much about it.

Nothing i can do about the ram usage, that's just how the game works. If you are talking about the additional textures then that's just me being lazy and not removing them. They aren't used in game if there exists HD textures for that entity.
