There are a few noteworthy changes in the latest Google Search update, but we've spotted one more that deserves some exploration. Ever since Google rolled out its new voice interactions as part of Google Now, settings control has been strangely absent. With v3.4 it's kind of there.
Update 6/30/14: Search v3.5 seems to have added Bluetooth support, but it still doesn't do what you really want it to.
In the new Google Search, you can say things like "turn WiFi off," and the device will automatically open the correct settings menu.
