looks great but how will it be if one has a lots of notification widgets will it just be endless scrolling?
For those of us who have had this features for years on other platforms, you will never have that many because you'll be clearing them as they come. Apps shouldn't be blowing up your notification screen, and you can turn them off. Games telling you that you have new lives, back ups telling you photos uploaded to cloud, etc.
And not being a smart alec, but seriously considering going back to an iPhone. It's finally almost got all the features I left it over. If I could just make Google Now the default over Siri (sorry Siri, you kind of suck) and change default maps, etc. I would not even hesitate.
