Is there a Windows 7/8/8.1 like automatic window sizer? so I got a Macbook Pro a few months ago to use for coding and as a DAW. Really the only thing I miss about Windows 8.1 is the ability to drag a window to the upper left or upper right corner and have it automatically resized to take up the half the screen. Is there an option in Yosemite like this, or a tool I can download? Found it to be a real time saver as opposed to fiddling with height and width.
BetterTouchTool has one of the features u are looking for.

You can find it in Window Snapping Settings:
