WinSplit Revolution
WinSplit is a Windows application that allows you to define areas for windows to be displayed. WinSplit works with Hotkeys — so you simply need to hit Ctrl-Alt-1 (number keys) to re-position the window you are currently working with to lets say the lower left part of your screen (you define these areas).
My 4K screen is set up as:
33%      33%      33%
66%      66%      66%
and then main window that appears in the center (like for programming).
