i played with an ics launcher on my TB,and you couldnt change the apps it had. i use adw ex or go,and like 5 spots on the launcher for camera/phone/app drawer/mms/email. then i like only sound hound,beautiful widgets weather and a battery widget on the main screen.
i have to re-adjust and put some of those on the homescreens when i run a sense rom with the sense launcher,so its not that i
cant... i just dont wanna,lol...
once im on a real ICS rom ill deal with it
