Holy crap, Aviate launcher is fantastic.
I wasn't expecting this launcher to be so good. Since it's still in alpha, it's invite-only. I got my code yesterday and damn, this is good. Essentially, it's like Project Kennedy/Google Now taking over your phone. The interface looks like a post-modern masterpiece and, surprisingly, using it makes a lot of sense. I won't mind if this was how Android 5.0 is going to look like.
