Ask HN: Is window management on OS X broken?

How is it possible to manage windows with multiple screens and multiple spaces using just the keyboard? (Tiling might solve this, but my main issue is productivity) This involves a set of simple features: * Maximize windows (Move to another screen and it is still maximized even though the screen is bigger, crazy right?) * Cycle windows (on just the current screen and space) * Focus another screen * Move windows to another screen or space * Optional: Move the mouse to the focused window I tried tools like Spectactle, Amethyst or Mjolnir, but it took only a few minutes to realize that something is broken or missing. Is this somehow possible? How do you solve this?
