When you open multiple toolpanes, you can display them in any of the following positions:
Individual docked or floating toolpanes
If you dock one toolpane in a vertical dock (left or right side) and another toolpane in a horizontal dock (top or bottom), the first toolpane you dock sizes to the full docking space, while the other toolpane resizes to fit the remaining docking space.
Stacked in a single docked or floating toolpane with multiple layers
Stacked toolpanes layer one on top of another, with the most recently opened toolpane on top.
The name of each toolpane in the stack appears in a tab at the bottom of the toolpane area. Clicking a tab moves that toolpane to the top of the stack so that you can view it. Both floating and docked toolpanes support stacking. When you move the stack, all of the toolpanes move at the same time.
Adjacent toolpanes sharing the same docked or floating area
Toolpanes can share the same docked or floating area. You can position toolpanes adjacent (side-by-side) to one another in any direction, above, below, left, or right. Adjacent toolpanes that share the same docked area (top/bottom for a vertically docked toolpane and left/right for a horizontally docked toolpane) display a Maximize icon in the title bar to expand the toolpane to the full docking area.

Note: When you position a toolpane above or below a vertically docked toolpane, or to the left or right of a horizontally docked toolpane, a Maximize icon appears on the toolpane's title bar. Click to maximize a toolpane to fit the entire docked area or to restore it to a shared size.
