Controlling window locations
From PowerGUI Wiki
Using the window-location control
The default script editor window configuration consists of 3 docked windows - the script window across the top, and two debug windows, one displaying variables and variable contents, and one a Powershell console. By default, the Variable window is on the left, and the Powershell console is on the right. A window's location can be changed by dragging its title bar. When this is done, the window becomes undocked and is now floating. To dock it, use the position control that appears when the window is dragged, as illustrated below.
