There is still no landscape layout when you rotate the screen, by the way, and I really can't think of any excuse why they are not allowing it. When I set the display scaling to 175%, I already get the UI that is designed for bigger, wider screens. I will try to post screenshots of that mode even though it's very buggy. (To be honest, the problem might lie also in the OS: at 175%, the task switcher does get the phablet layout, but only appears the first time you long press the back button, afterwards nothing happens - as if a task switcher were never there).
