I'm new to the world of Macs, having only been familiar with iPhones and iPods for the past few years. Now that I have a MacBook, there's just one thing that I'm really missing from Windows 7: The snap feature that allowed me to drag one window to the left and one window to the right and they would automatically be resized to be shown side-by-side on the screen to allow for easily going back and forth. Example: I've found about one or two possible solutions in the App store but they're not free so I wanted to ask around before proceeding. Maybe there's a third party application that can do it... Anybody have any suggestions?
