It seems that we finally have something to go off of in regards to all the new design tweaks we have been seeing with some of the Google apps. Most of you have probably already noticed that there have been some design changes happening to some of the apps from Google that most of us probably use on a daily basis. We thought we knew this project to be called Hera, but that isn't entirely true. Hera is more about bringing a unified Chrome and Search experience to the Android platform. These new design changes are actually part of something that is called Quantum Paper, which is Google's massive project undertaking to give users a consistent fluid user experience across all platforms. So that means Android, Web, and yes even iOS.
Google wants to streamline the experience users have no matter what platform they're on, and Quantum Paper is how they're going to deliver on that goal. This unified design framework is already starting to make its way into Android, as the design changes have begun with Google+. The update to G+ that happened not too long ago was the first step Google took as part of Quantum Paper to begin uniting the experiences together across platforms for an elegant and beautiful design within apps. We'll being to see these changes take effect in web apps as well as design within iOS in the future too. Officially though, it's said that we won't be seeing or hearing anything about Quantum Paper and the goals behind it until Androids next major release version, or version "L".
Tweaks and and changes to the design aren't limited to the UI as a whole either, we'll see changes to the icons within Google apps as well. Some of which again, that we can already see within Google+ like the new search icon and the "write something" button down at the bottom of the G+ app. The Quantum framework will eventually be open to third party developers too, so this new elegant design framework for a consistent UI and consistent user experience will be able to translate to other apps beyond those from Google. As Android Police points out, you wouldn't be completely in the wrong for thinking of Quantum Paper as Google's replacement for "Holo". However it isn't just about replacing the design guidelines for Android apps, it's about making for a more unified and consistent user experience in addition to the UI across multiple platforms and not just Android.
