That changed in Windows 7 with the arrival of Aero Snap, a feature that let you drag a window to the left or right edge of the display, where it would “snap” to that edge and occupy 50 percent of the width of the display. Microsoft finally added overlapping window support to Windows with version 2.03-and yes, Apple did sue, for that and other Windows features that it claimed copied the Mac-and for the next decade and a half or more, the ability to cascade and stack open windows were the only notable window management innovations that Microsoft added to the product. Instead, windows were full-screen or, when used with other windows, would automatically tile to fill the available space. The roots of this feature date back literally to the earliest days of Windows, when Microsoft, fearful of an intellectual property lawsuit from Apple, decided not to support arbitrarily-sized floating and overlapping application windows. Snap is a productivity feature that helps users arrange applications and other windows logically on-screen. In Windows 11, Microsoft is improving the Snap window management feature yet again with new features.
