What is the magnet button when I place items?

When you place a box, furnace or another item on the floor, the magnet button appears next to CANCEL. With the MAGNET on, the item sticks to walls, corners and to other items of the same kind, so you can line them up neatly in a row.

Tap the magnet button to turn it off and place items freely. It's on by default and remembers your choice.

The ROTATE button now only shows for items that can be rotated.
