This request/question comes up a lot so I figured I'd make a separate thread. So you've just started housing, putting in little details and you've noticed your home is now sprinkled with little white arrows that distract from the rest of the house's aesthetics. What is one to do? Get rid of them, the option is already in game!
But where? Here:
Character Config > Display Name Settings > NPCs tab > Housing Furniture
(also an option for the garden below there)
Enjoy your new arrow-free environment!
