Admit it. Google Now, specifically the "OK Google" trigger, is quite fun to use and play around with, but it's actual utility isn't as impressive. That's largely because, aside from the web and a few other Google-owned apps and tools, its repository of data doesn't dig deep enough into your phone and its apps. Well, not anymore. Your favorite "OK, Google" can now search inside any app, too! Of course, app developers will need to add the feature, but it's as easy a copy and paste.
