Jane Manchun Wong has fun with examining the code within applications looking for hidden new features, security vulnerabilities, and references to new upcoming products. Recently, she took to Twitter to reveal some possible upcoming new features to Spotify.

Editor's Pick Spotify for two? Premium Duo could be the answer Spotify is testing out a new premium plan that offers two subscriptions over the six that are currently included with the Premium for Family plan. Called Premium Duo, it appears that plan has its sight …

This isn’t the first time Wong has uncovered new app features simply by poring through publically available code. She’s found hidden features in apps from Instagram, Facebook, and Google-branded apps, all of which were eventually released. You can read all about her methods — and how she does this without any interest in financial gain — over at The Next Web.

The new Spotify features Wong found were in the Android app. The first thing she discovered is a sleep timer feature, which would allow a user to play a track or playlist for a certain amount of time and then automatically stop. This is helpful for those who like to listen to music while falling asleep.

Wong also found a feature related to connecting with friends on Spotify. You’ll be able to use a custom scannable code that will easily allow you to share songs with people you know. Simply have your friend scan your code — which looks like a sound wave rather than a QR code — in the “Connect to a device” section of the app:

The final new feature Wong found allows for easy Spotify integration with various navigation apps, including Waze and Google Maps:

We don’t have any idea if or when these features will actually land on the Spotify Android app. However, Wong usually discovers features a few months before they launch, so it might be a while before we see all these. Of course, there’s also the possibility that they won’t land at all.
