[xmonad] Ratpoison style focus

Hi xmonad friends, I am a long time orphan of ratpoison, and after trying ion3, dwm, awesome and many others I finally settled on xmonad + kde. Simple to configure and a joy to use. Great work. The only thing that still bothers me is not having ratpoison-style focus, which means separated mouse and keyboard focus. I find it very useful for writing code in my xterm (konsole, actually) while I use gmail from a browser in another window. This prevents long mouse trips between the browser and the terminal (and these monitors keep getting bigger and bigger). Any hints? Is this something possible to achieve with existing contrib extensions? I couldn't find anything. -- []s Davi de Castro Reis
