I was once a Macbook user several years ago, but then switched to Windows due to work. Now I am back to a new MBA. Once feature I dearly miss is the snap to side feature. Essentially, if you drag the title bar of a particular window to the left or right of the screen, it'll auto resize the window to fit half the screen. You can do this with another window, and thus have two windows open at the same time. How can I replicate this feature on my MBA? I downloaded an app that was supposed to do this but it didn't even come close...
