Activating and deactivating PSM in MeeGo is a pain for me, having to start the Settings application, select Device and then Battery and finally click on the PSM button and select On. It’s a 4 steps procedure that at least consume me 1-2 seconds. Smartphone is meant for simplicity as well as quickness in operation.
Hence, a Toggle PSM button on the laucher home page which triggers the PSM on a single click on the home page. It’s just as easy as it looks.
