How do you move things
1) Tap Design Mode button (on the lower right)
2) Tap the category tab of the item you wish to move (so if it's a furnishing, tap the 2nd tab for furnishings)
3) Tap & hold the item you want to move (it may help if you zoom in)
4) Drag the item to the place you want and double tap to confirm placement
You tap and hold
What is the point of the having the things in the third tab in your house on the game
To move things tap it than hold it
The Design Mode button is the Store button :)
There is no button on the lower right
To move a room, make sure you have the Room Tab selected in Design Mode. Then tap and hold the room you wish to move. Once it turns green, you can drag it to anywhere you would like in the house. Double tap to confirm.
The sell dialog will also come up in edit mode but you do not have to drag your room there to sell.
