Re: Sims 4 - Postcard & corkboard
The cog cursor tells you that it's drag interactive, meaning you can drag itself or something on it. I hung my postcards on the board by selecting the card in the inventory and pressing "x" (I am on X1, on PS it should be the square). After that it held the card in the cursor and I could drop it on the board. There is no interaction but a drag target on the board afaik.
