I'm always changing things up, usually switching between a heavily customized Nova Launcher setup and a simple and straightforward Google Now Launcher setup. Right now, I'm on the simple GNL setup. I've been stuck on using Tapet for my wallpapers for a while now with the master mode switch set to on, so I have the thumbs up and thumbs down buttons to improve the automated wallpapers for my liking. And some folders to quickly get to my most used apps.
Yeah I thought Backdrops was nice when I first downloaded it, but quickly realized they didn't often have things I liked. Tapet has been pretty cool though. If you thumbs up, it doesn't change it again right away, it will just change at the next interval time. If you thumbs down, it immediately generates a new wallpaper and applies it. When you thumbs up, it learns the colors and layouts you like more and is supposed to result in better wallpapers for you.
