Add the possibility to arrange applets in multiple rows

It would be great if there where the possibility, in AWN, to arrange applets in multiple rows. (Like the applet of Notification Area or Indicatr Applet.)

This can be done adding a "layout applet" that creates a grid where to put needed applets in multiple rows (for example keep four weather applets in the same places where now there is one in a 2x2 layout) or keep 4 menu applets/staks applet in the same place where now there is place for one applet.
