Pro Define OS X window buttons
AROW enables you to change the actions of OS X’s window buttons. It only requires either a right or a left-click for the action to take place.
Pro Smart Panel to move and resize windows
The customizable grid panel is very intuitive and is an accurate way to resize and move windows. Simply drag your mouse across its grid, the window will be moved, and resize to the exact position instantly.
Pro Easy ways to snap windows
Simply drag windows to the edges of your Mac’s screen. Once the cursor reaches the screen’s edge, the window will automatically move and resize to fill exactly half or quarter of the screen.
Cons
Con Does not support the border of multiple displays well
When using multiple displays, the ability to dock a window to half of a display only works on one side of the screen divide. It can work (with some very careful cursor placement) only on the external monitor and not dividing edge of the native (laptop) monitor. It does not support quarter-splits either.
Bottom line, this was a great initial app, adding this capability before anyone else did, but it has been eclipsed by newer apps.
Con Trouble with GUI
Yosemite (10.10.5) it works but it's impossible to open the application GUI.
