This was pretty close, but ultimately was too i3-ish for me. I'm also realizing that I could never be as productive with i3 as I am with a mouse or trackpoint -- with a trackpoint I never have to change my hands out of root typing position, whereas to hit any of the key combinations involving the super key, I have to move my left hand to a whole different, scrunched position. Don't know how you guys do it.
