Perfect!

Maximize windows with a keystroke (a real maximize, not the new “full-screen” thing). I set up Cmd-[NumPad Key] to put things where I want them. Cmd-7 puts a window into the upper left quadrant of the screen, Cmd-9 does upper-right quadrant, Cmd-8 Fills the top half of the screen, Cmd-4 uses the left half of the screen, and so on. I mapped Cmd-5 to maximize the window to the full screen. This utility has raised my productivity. 5 stars!
