What software is available changing the default maximize button behavior in this video? The still from this video (see image below) shows non-standard window maximization control options. Upon mouse hover on the + in the normal close, minimize, maximize controls (top-left of each window), a pop-up bubble is shown.



How can I enable these maximization options for my Mac?
That's Moom. Very handy app for various window management.



The site has a general options list as well for the window management category at: What Window Management Options exist for OS X?
