BetterSnapTool allows you to easily manage your window positions and sizes by either dragging them to one of your screen's corners or to the top, left or right side of your screen. This lets you easily maximize your windows or position them side by side. In addition to that, you can set keyboard shortcuts in order to move and resize your windows the way you want. BetterSnapTool is very customizable and will change the way you work with your Mac - it supports multiple monitors and hidden dock. You can change the design of the preview window and even set application specific snapping sizes.
