On my previous phone when I was placing items on the dwsktop, such as, anot app or widget, I use free mode. On the previous phone when I had the icon aligned vertically and horizontally with another icon, lines would appear and the icon background would change. I cannot find the setting for this on lightning lauch on my new phone to save my life. Can someone please tell.me where this setting is to make alignong objects so.much easier? Thank you
