As Google continues to unify its various products into a larger Google experience, yet another small, but notable feature has been spotted.

You can now share apps from Google Play on Google+, and Google will automatically add an install button, so users can install the Android apps right from their Google+ streams, without having to click through to go to the Google Play store.

As Matt Brian at TheNextWeb points out, this happens if you paste a link to an app from Google Play to Google+, but the install button doesn’t appear if you simply share the app from Google Play itself (for some reason). I would expect that to change.

Anyway, here’s what it looks like:

As Brian notes, Google has had similar integration with Music on Google+ since Google Music launched, when you could share previews of songs with friends. Movie downloads still do not work in this manner. Yet. It seems like there would be some good Hangouts integration opportunities here.
