Moom makes window management as easy as clicking a mouse button—or using a keyboard shortcut, if you're one of those types of people. With Moom, you can easily move and zoom windows to half screen, quarter screen, or fill the screen; set custom sizes and locations, and save layouts of opened windows for one-click positioning. Once you've tried Moom, you'll wonder how you used your Mac without it. Hover the mouse over any window's green button, and Moom's pop-up palette appears. Quickly fill the screen, or move and resize to vertical or horizontal halves on screen edges. Want quarter-size windows instead? Hold down the Option key, and the palette presents four quarter-size corner options, along with center without resizing.

FancyZones is a window manager utility for arranging and snapping windows into efficient layouts to improve the speed of your workflow and restore layouts quickly. FancyZones allows you to define a set of zone locations to be used as targets for Windows on your desktop. When you drag a window into a zone or enter the associated keyboard shortcut, the window is resized and repositioned to fill that zone. You can also trigger zone selection mode by clicking the non-primary mouse button if the "Use non-primary mouse button to toggle zone activation" setting is enabled. If two zones are adjacent, a window can be snapped to the sum of their area (rounded to the minimum rectangle that contains both). When the mouse cursor is near the common edge of two zones, both zones are activated simultaneously, allowing you to drop the window into both zones. You can drag the window until one zone is activated, then press and hold the control key while dragging the window to select multiple zones.
