AROW
AROW is a lightweight and efficient app that makes it as easy as possible for you to arrange, resize, organize windows in ways that are just above OS X’s capabilities. This said, AROW enables you to quickly manage your windows with the help of keyboard shortcuts, by dragging the windows towards the edges of the screen, or by changing the default behavior for OS X’s window buttons. In order to get started with AROW, you must first authorize the application to control your Mac. In order to do this, open System Preferences, click the Security and Privacy icon, in the Privacy tab, select Accessibility from the list, unlock the settings, and click the checkbox next to AROW.
