The direction I predict (and hope) android UI is going.
Android is my favorite mobile OS, not hands down, but close. The apps are no longer an issue, lag is no longer an issue, and for the most part, Google's design is no longer an issue. When I say Google, I mean youtube, gmail, google search, and so on. What I do not mean is android, while I love the pushes to holo design language within apps, the android home screen still remains essentially the same since the 2008 debut on the G1. A grid of apps and widgets, and no real cohesive design, just icons floating in space, all different sizes (one thing no one person can fix besides the developer of the app), it just still seems like a mixed bag of aesthetics. Google now looks completely different from the android homescreen, with different shading and balance. What I wanted to do is bring the very nice looking google now to the homescreen of android, and make things look less stark/black and faux glass, and more grid based, grey, and quite honestly, metro. Windows phone is leading the charge in design, and I think if Google takes android to the Google now route of design, Microsoft would have real competition in terms of beauty.
The homescreen when you boot it up would display either Google now cards, or widgets of your choice. The app dock on the bottom wouldn't be the only place to access your favorite apps, you could make multiple docks and name them whatever you want like a folder.
You could even swipe app docks out of the way, save them, stack them, or arrange them to show only on certain days. You can 'pin' app docks to never be swiped away, so you can have them always at hand.
The OS itself is less swipe focused on changing pages, because you could accidentally swipe away a google now card, so instead it focuses on either swiping above the user grid, near the top user changeable background, or by tapping 'apps widgets home settings' itself.
Getting to your apps is no longer hidden behind an app launcher icon, rather it sits next to your home screen, tapping the apps or widgets will display every app on you device. When you go to the widget tab, you can select a small amount of widgets to be live there, then under your selected widgets will display all other widgets to be put on your home tab.
Tell me what you think, do you want android to go under a full overhaul, or do you like the home screen as it is? Would love some feedback as well, would you use this? Thanks.
