Here's one just for you. I hope you get to grab it: FLHLJJ777L3L
I'm kinda sleepy in my office and just copied and paste the code for fun, didn't expect it to work (or maybe can I reverse the procedure? I never used 'redeem' before :-/ )
HOWEVER, bought a copy after reading through the comments / MAS reviews - it's pretty neat!
I'm generally working full-screen, but for the few times when not it'll be a life-saver. I lost so much productive time recently getting distracted by IRC in the background :P
