first of all: an armory (or armorer NPC) in which we can storage Arrows, Weapons and Armors, NSCs will pick up automatcally the Fitting items.
We would not have to run in circles to see if every nsc has got arrows.
more intense farming System: having chickenhouses (produces eggs and meat) , swinepit, bigger fields to grow Things on.
a gatherer Station from where we can send out nsc to Gather herbs, meat and fruits?
*PLS: Named Thralls for workbenches should at least get some clothes
