Screen Regions

Screen Regions is a free utility that allows you to create and save window layout arrangements. This is most useful for people who use multiple monitors, especially 3 or more. and who do tasks having a large number of different windows open at once. With Screen Regions you can save a layout and then pick it again later and instantly snap all your windows to their saved locations by clicking the "Resnap all" button. And they don't have to literally be the same windows- Screen Regions intelligently guesses which windows should go where based on which applications' windows you had saved where.
