SnapIt

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.

BetterSnapTool allows you to easily manage your window positions and sizes by either dragging them to one of the screen's corners or to the top, left, or right side of the screen. This enables you to easily maximize your windows, position them side by side or even resize them to quarters of the screen. If you need even more than those standard snap areas, BetterSnapTool now allows you to create your own, custom snap areas anywhere on your display. Other features include custom keyboard shortcuts, customizing clicks on window buttons, moving/resizing windows by holding a key, and many more.
