UPDATE: SharePoint Online team sites + Office 365 Groups moving beyond First Release

Office 365 Groups do solve a much needed problem that traditional SharePoint sites however the navigation is not consistant and the applications do not all look the same.  When moving between Planner, Word and One Note...they all have different button and navigation.  In some instances, I cannot figure out how to get back to the "group conversation landing page".  Governace is another issue as there are a few ways to create a group that need to be locked down from a centeral location.  Please keep this in mind as you further develop this great new addition to the Office 365 suite.  I know Teams are coming in the near future and that will further confuse users if there isn't clear guidance on how these tools are used and surfaced in the platform.
