When I open volume controls I see a slider for alarms.
My only current gripe is that the "OK Google" detection is not very good, I have to hold the phone very close for it to detect.
That is one of the main bug fixes for the new update we haven't received yet

Fixed Camera "O" gesture activating lockscreen instead of triggering camera

You may have spotted the "Clear Image" as an added feature. OnePlus One is so proud of it, it got its own announcement in the company's forum. It states:
"Clear Image is your camera on clarity steroids. It's your camera over 9000. Once you switch on the new Clear Image mode in the Camera app, nothing but awesomeness will be captured. 10 individual photos are stitched together for a final super high-res photo when you snap a shot. Through interlacing and compression algorithms, the camera improves clarity, reduces noise in low light, and adds detail that other cameras cannot. But this is not all. Unlike other photo stitching software, Clear Image minimizes file sizes while maximizing for quality."
