I would like to re-program the home button to close the current(on screen) app when pressed and held down for about 3 seconds. Any idea? - I know about double clicking and holding down icons until they start to shake and then closing one by one. That is not what I am looking for. - I know about force-quit feature using a combination of sleep and home buttons that takes 10+ seconds. That is not what I am looking for. - I know that leaving apps open does not necessarily take up memory. I still need to close certain apps once I am done with them.
