I know on the Desire HD ported (Pure Sense) ROM am I running my MT4G if you long press on any of the home screens one of the options is to have a folder on that home screen (just like how you change the wallpaper) anything you don't want on any of the home screens, just long press on the icon and dreg it to the trash can icon that will pop up at the bottom. to put any apps icon you want on the home screens, open the app drawer and log press on the icon you want to "shortcut", the home screen will come up just drop it where you want it. if you want it on one of the side screens just move the icon to which ever side you want to scroll to and hold for about a second and the screens will start to scroll, just drop it on the one you want it on.
