1.3.1. Using flaps, tabs, and palettes
If you drag the innermost edge (the right edge of the left flap, the left edge of the right flap, or the top edge of the timeline flap), you can change the width of the flap.
Tabs have title buttons:
If a tab title button is double-clicked, the content of the flap is hidden, though not the. The same thing can be accomplished by clicking the X icon in the upper right of the tab's title bar. Hidden tabs look like this:
The title bars of tabs and palettes also have controls on them; to the right of the tab or palette's title are buttons. These buttons allow tabs or palettes to be hidden, maximized, or pinned. Palettes can be dragged by their title bar to become 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.
