Mission Control: Death to Window Clutter

In its day, the concept of overlapping windows on the screen was brilliant, innovative, and extremely effective. (Apple borrowed this idea—well, bought it in a stock swap—from a research lab called Xerox PARC.) In that era before digital cameras, MP3 files, and the Web, managing windows was easy this way; after all, you had only about three of them.

These days, however, managing all the open windows in all the open programs can be like herding cats. Off you go, burrowing through the microscopic pop-up menus of your Dock, trying to find the window you want. And heaven help you if you need to duck back to the desktop—to find a newly downloaded file, for example, or to eject a disk. You’ll have to fight your way through 50,000 other windows on your way to the bottom of the “deck.”

Mission Control tackles this problem in a fresh way. The concept is delicious: With one mouse click, keystroke, or finger gesture, you shrink all windows in all programs to a size that fits on the screen (Figure 4-10), like index cards on a bulletin board, clumped by open program. Now you feel like an air-traffic controller, with all your screens arrayed before you. You click the window or program you want, and you’re there. It’s fast, efficient, animated, and a lot of fun.
