I have plenty of Android apps that run full screen on my tablet, so this is no proof to my eyes. Ok, now I see it but it was not that easy to see and also it is not exactly part of the UI (just to nitpick a bit ) But at the same time, no "real" Sailfish UI element anywhere (pulleys, glass-effect app background, app navigation by swipes, etc.). I now see that you probably are right, but I still think it is not that crystal clear! Anyway, if so, better.
