The Flip Main window item allows you to flip between a vertical and horizontal layout for the MeshTV Main window. When the layout switches to vertical from horizontal, two windows are displayed, regardless of how many windows were shown when the Main window was vertical. Likewise, when the layout switches from horizontal to vertical, one window is displayed, regardless of how many windows were shown when the Main window was horizontal. Note that no windows are deleted by this command, but a second window might be created.
