Adding a new panel?

I accidentally deleted the third panel (the one on the right side from the Home panel). How can I get it back?

Drag an icon to the edge of the desktop-panel, where no next panel is. If you drag it over the edge there appears a new panel. One of the panels should be the home-panel. Push the round button at the bottom and you get the home-panel.
