two things ive been meaning to ask.

can i easily change the background on this page with the GUI id like something more personal as i see it quite often.

secondly is it possible to put a new sms / email / other notification icon on this page, so i dont have to unlock the device or wait for an led flash to check to new notifications

its so easy to press the hardware power button to glance at this screen it seems logical you would have some info on it.

also what is this screen called, id like to see if i can find out more by searching a specific term

thanks
