The Google app for Android recently got updated to version 4.1, and in the process it gained a “Now cards” section in its settings and several smaller tweaks. However, it looks like the code of that app holds hints to bigger changes that might be coming.

The folks at Android Police took a dive into the code of version 4.1 of the Google app and found several interesting tidbits. The screenshots above show a new feature that allow actions activated by the “Ok Google” hotword to just appear as an overlay over your current activity. Currently, using “Ok Google” to do things like compose a text message will place your current app in the background and launch the Google app.

Another major feature hinted at in Google v4.1’s code is support for notifications that can be read aloud. The code for this Google app update includes a line that reads “Read notifications aloud when” followed by things like “Using Bluetooth or headsets.” This suggests that users may be able to have their notifications read to them when they’ve got a Bluetooth or hands-free device connected.

The new goodies don’t stop there. Other new features hinted at in Google v4.1’s code include power toggles in Google Now, support for sending text from your computer to your phone, support for third-party apps (possibly only select ones), and more.

It looks like Google’s got some big plans for its main Android app. The ability to have notifications read aloud to you could be big for folks when they’re unable to access their phones, allowing them to stay in the loop and not have to worry about missing an important alert. Support for third-party apps in Google Now could be huge too, even if its only for select apps, because it would make Google Now even more of a “go-to” source for information.

What features would you like to see added to Google Now in the future?
