There will be a limit to the amount of items to be kept in one room:
From Stardoll:
Hi Catdog-runs, thanks for getting in touch with us. This is a new function. In the main room, the maximum is one hundred. It hasen’t been determined yet for the other rooms.
You can move around your mirror and shelves! And you can change other people’s hair, makeup etc. New icon images. More arrows to move left/right around the suite. Also the view of the small house map has changed: now it also says how many items are in each room.
