Several palettes can be joined into one large super-palette. To do this, drag a palette to the bottom edge of another palette group. An outline will appear long the bottom edge and then you can release the mouse button. The two palettes will become attached, but not overlapping. You can adjust the height of each palette group by dragging the divider between them.
You can attach several palettes this way to create one massive palette collection. This can be useful if you use multiple monitors and you want to move all your palettes to a second monitor. By docking all the floating palettes together, you only need to drag one thing to move all your palettes to the second monitor.
