To add a new home screen panel:
Touch and hold an item such as a shortcut or folder on the home
screen and drag it to the right edge of the screen to create a new
home screen panel and put the item on it.
NOTE:
No empty home screen panel is allowed to exist. If the shortcut or
folder is the only item on the current home screen panel, the
panel will be deleted as you remove the item.
