Android L is overflowing with new features and clever little tweaks, but none of that will be official until later this year. Not wanting to wait around, the CM folks have already borrowed (or "kanged" if you must) a feature from Android L. In the 0701 nightly builds, there is now a handy universal settings search button.
Just pop open the main system settings and there will be a search icon in the upper right corner. Tap it and you can enter any search term you like and get results in a drop down. The UI is still a bit different than what happens in L, but it gets the job done. A few OEMs (like Samsung) have done the same thing – it's not a huge innovation, just commonsense.
The original announcement of this feature was deleted from Google+, but the CyanogenMod reshare remains for right now. I'm not sure why it was removed, but the feature is definitely live as seen in our screens. Go ahead and flash, if that's your thing.
