This post takes a closer at behind the scenes of designing the Aero Snap feature in Windows 7. With Aero Snap you can grab a window and move your mouse to the edge of the screen and the window will resize to fill half the screen. Repeat with the other window. Now with two easy motions you have a setup that makes both of these scenarios much easier to accomplish! Now, with Aero Snap you can you can maximize a window in the vertical direction only. When you resize a window to the top of the screen, it will also resize all the way to the bottom. Great for reading long blog posts!
