Re: Android KitKatŪ Wish list!
Keep in mind that the notification drawer already offers a lot of functionality through customized notification layouts, action buttons, etc. Many applications simply don't take full advantage of this. It's also important to keep in mind the importance of clearly-defined and non-overlapping UX elements. The notification shade should serve as a notification shade, with persistent notifications fulfilling the requirement of things like music control. When you look at the Play Music 'now playing' notification and the Play Music homescreen widget, you'll notice they're very, very similar. It's a good idea, though one that's occurred to me before as well. I wouldn't mind seeing improvements to the stock launcher, perhaps adding some additional control and customizability while keeping things streamlined.

For the most part, those features can work through software alone, but in order for them to work well and not drain your phone's battery, there are hardware dependencies that must be addressed. Without the contextual awareness and natural language processing cores, the Moto X wouldn't be able to do what it does without preventing the device from going into deep sleep. Furthermore, the Active Display functionality is reliant on AMOLED display technology for its ability to power individual pixels separately. Again, you can replicate this feature on devices without AMOLED displays, but you're going to see a drastic hit in battery life.

Though it may not be the most widely-used feature, I get a lot of benefit out of it both with my own devices and with friends'. The same could be said for WiFi Direct, which required WiFi Direct-compatible hardware (though that was more of an incremental feature addition than a standalone one).
