Apple's Latest 0.1 Adds a Lot: "In terms of pure productivity power, Panther's most important perk is a new anti-window-clutter feature called Exposé. When you press a certain keystroke (of your choosing), all windows in all programs visibly shrink and array themselves across the screen like non-overlapping tiles. You just click the one you want to bring it forward at full size. This visual method of plucking a window from a haystack is so brilliant and addictive, you'll wind up using it dozens of times a day. Exposé is the biggest graphical breakthrough that operating systems have achieved in years."
