Options can be moved between columns of the same width. To move an option, click on any part of its option bar, as shown in figure 1, except for the add and delete buttons, and hold the mouse button down.
You can then drag around a box which is the same size as the option, as shown in figure 2. Whenever the box is moved over a position where the option can be dropped, the option will move to that position. When you let go of the mouse button, the option will be left in its final position.
