That's pretty brilliant, press and hold a X mark shown in task manager and drag it over to the app to close it immediately upon releasing it. Kinda like where THC's sense can unlock the screen by dragging the unlock icon to a field or an app (where in this case, you immediately open up that app). The task manager shows your last used apps firstly thus reagganging on the go. So probably a no for rearranging in task manager. On a side note, I heard some speculation about a closed down UI is that true? would be bad for modding. I'd hate to jailbreak something that is named Maemo6/Harmattan, sacrilege!
