If you have iOS 7.1 Beta, how are you liking it and what are your favorite features???

I just downloaded it on my iPhone 5s, and so far, I'm absolutely loving it. My favorite feature are the speed improvements around the whole OS. My iPhone just flies without stopping. My second favorite feature is the dark keyboard, to me it looks pretty sexy and beast, it's so much better than the white keyboard. And all the other features area also very welcome, but I felt like listing my favorite features.

So, fi you have iOS 7.1 beta, how are you liking it and what are your favorite features???
