When Microsoft unveiled the Windows 7 upgrade several years ago, its unique Aero Snap window manager quickly became a fan favorite. Aero Snap lets you drag windows to the edge of your display to maximize, minimize or split-screen them. BetterSnapTool brings all of this functionality — and more — to OS X. You can configure the software to snap windows to whatever area of the screen you like. At $2, it's definitely worth the price.
