The Ever-Changing Palette

Many Illustrator palettes have more than one display size in some cases, multiple sizes. You can use a palette's flyout menu to choose Show Options or Hide Options, but it can be faster to double-click on the tab at the top of the palette. To see if a palette has multiple sizes, just keep double-clicking on the tab to switch among the collapsed, basic, and expanded views. (Why collapse palettes? To save space without closing palettes or to move them out of the way.)
