Google App Easter Egg - "Bells and Whistles"

I was posting something on Apple's Discussions about the change in the Google Mobile App - a poster was lamenting the change to the mobile-optimized format. I like the classic view better, was searching for a way to change it to that in the Settings during a football game... My point follows.

I was in the app's Settings screen, fiddling with it by scrolling up and down a bit during the review and not looking at the screen - nervous habit, I guess...

After the TD, I stopped fidgeting and looked back at the Settings screen, and there's a new menu at the bottom of the screen I swear wasn't there before called "Bells and Whistles". There's four new settings, following with an appropriate descriptions.

* Theme Color.
* Sounds. Default, Chicken, Monkey.
* Live Waveform. While using the voice search, the waveform matches the intonation of the sound.
* Open Link in App. I like this one - linked results in the app don't launch the Safari browser and lose your search results; and a new navigational bar appears at the bottom of the app.

Don't shoot the messenger. A buddy watching the game didn't have the extra settings, but just kept scrolling down for a few minutes and the extra settings just showed up and stuck after that.
