During my day job I work on a Windows PC. The current operating system I am running is Windows 7. One of the nice features that I actually like from Windows 7 is the Snap feature. Windows Snap allows the user to resize open windows, simply by dragging them to the edges of your screen. This makes it real easy to compare and contrast documents on one screen. I find it strange that OS 10.8 has not implemented this feature as of yet, but never fear a third party program exists.
The program I am referring to is Cinch from Irradiated Software. “Cinch allows you to precisely resize a window simply by dragging to the left, right, or top screen edge.” Cinch is as advertised and a little more. As the video below demonstrates, Cinch also takes advantage of the full size feature in OS 10.7 and above by dragging a window on the task bar snaps the window to a full screen. Additionally, it works with a dual monitor setup and reverts your window back to its original size when you move it back.
The App is available either through the Mac App Store or Irradiated Software’s site for $6.99 or $7.00, respectively. The only difference I could tell between purchase portals is that the website offers a 60-day money back guarantee. Additionally, you can downloand try Cinch for free.
