BIG Launcher allows you to have unlimited number of screens. When you add a new screen, it can be automatically linked to the previous screen. This means that lower right button from the previous screen will lead to the new one.
Now you can configure the shortcuts on the new screen. You can choose any application or contact. You can also choose a different icon for any button. The icon of the screen determines what image is shown on the button which leads to this screen. If you want, you can also select custom background image.
Now, when you go back to your home screen, you can see the custom icon you have selected. And the custom icon for your selected button. The lower right button which was replaced on the home screen has moved to this new screen.
