1.3.1. Using flaps, tabs, and palettes
If you drag the innermost edge (the right edge of the left flap, or the left edge of the right flap), you can change the width of the flap. This may resize the book desktop and the other flap.
Flaps, tabs, and palettes have title buttons:
If the title button is double-clicked, the content of the flap, tab, or palette is hidden. The same thing can be accomplished by clicking the X icon in the upper right of a flap, tab, or palette's title bar. Hidden palettes look like this:
And a minimized flap looks like this:
Double-click the title button again to unminimize it.
The title bars of flaps, tabs, and palettes also have controls on them; to the right of the flap, tab, or palette's title bar are buttons. These buttons allow flaps, tabs, or palettes to be hidden, maximized, or pinned. Palettes can also be floating, rather than docked to the sides of the application window. A floating palette looks like this:
By clicking the buttons in the upper right of a floating palette, tab, or flap, you can cause it to return itself to its original docked position. Clicking the X will hide it; clicking the palette title button in its tab will show it again.
