Android 4.4 on the Nexus 5 came with a new look and feel. When I got the update to 4.4 on my Nexus 7 (2012) there was no new look. Of course I knew about the new Launcher being exclusive to the Nexus 5 only before updating but still, it felt a bit sad.

As I wanted a new look for my Nexus 7 too, I simply installed an other Launcher.
