Snap in Window Manager

You can resize and reposition (maximize, left half size, top left quarter size, etc.) a window by dragging the window to the edges or corners of the display. If you resize the window to half size, the thumbnail list of windows on the desktop is shown, then you can resize and reposition other windows to the opposite side of the resized window. When you change the width of a window with windows arranged on the left and right, the other window will automatically resized to fit it.
