I'm not familiar with that button, or maybe I've seen it and that was just an app launcher. What I was thinking it's something like a full blown start menu replacement, like the apps popping up when Win8 was launched because people wanted the start menu back. I can see how even Win10 menu could be improved and Google could use the opportunity to step in and brand that side of Windows and collect data about Win users.
