I'm just finding it a waste of time always having to shuffle my hands, having to go to the home screen, go into immersive mode, or waste a key for the notifications shade shortcut. It would be nice to just have it at the bottom, below the navigation bar - if possible! I mean, it would work either way: portrait or landscape. Plus, I don't think it's that troublesome to have the time and notifications on the bottom. Wouldn't it be great to be able to reach the quick settings easily, having it placed at the bottom half of the screen?
Who knows? Maybe this can be the next trend in smartphones - as the screen sizes are getting bigger and the UI & UX are becoming more gesture based!
