I had this question up before and had no replays at all.. so I had a look around.. the best thing I found without devoloping was perfect task switcher from the play store.. give u a sense 4.0 looking task switcher and you can slide to kill apps.. only difference is u can set it to launch using long press on the search button which I did... as I am now back on cm9 I hadn't bothered keeping trying for answers
