I guess I'll toss in the most boring home screen...
I keep a black background to save power, PowerTools to set up one touch (almost) access to settings, a few folders up front. Page two has more folders and settings. I use Greenify to kill a few select applications with a single touch. BB Hub and Keyboard, too.
(I've only had the 6P for a few days now and picked it to ensure that I will get updates and not have to wait on Verizon. My other choice was the Priv but I've never seen one and the local store doesn't have it and who knows if Verizon will be good about getting the updates out. Besides, I do appreciate the pure Android environment.)
BTW, the screen capture was taken 10 hours after pulling it off the charger. 94% although I had to admit today was a fairly light usage day.
