Floating and docking panels
We can drag and drop individual panels to create vertical stacks or horizontal tabbed groups that maximize the workspace while keeping options handy. Figure 4.6 shows a tabbed panel group, a panel stack, and a free-floating panel.

Note: Tabbed panel groups (left) are more space efficient than stacked (center) or individual floating panels (right).
     
 To group, dock, or stack panels, follow these steps.

1. Grab the panel (or panel group) by clicking on the top gray bar of the panel
2. Drag the panel until it overlaps another open panel or panel group or until it is close to a side or to the bottom of your screen
Caution: Do not release the mouse until the panel is ready to dock!
3. Release the mouse, and the panel should remain docked or stacked.
Unstacking or undocking panels is easy: Just click the top gray area (or tab) and drag to pull any panel away from the other panels in a stack or group and make it free floating
