SizeUp allows you to quickly position a window to fill exactly half the screen (splitscreen), a quarter of the screen (quadrant), full screen, or centered via the menu bar or configurable system-wide shortcuts (hotkeys). Similar to "tiled windows" functionality available on other operating systems.

Additional features include moving windows from one monitor to another, from one Space to another, and restoring a window to its original size and position (SnapBack).
