Consistent UI: Helps to keep users in context via a new card design for switching between document info, business cards and Yammer conversations.
Improved the Updates section of business cards: scrolling up the updates list hides the person details, leaving more real estate for updates (when you scroll the list down, the details re-appear).
Version 2.2 (January 12, 2014)
Yammer profiles and discussions: View real-time Yammer conversations in the Updates view. In the Enterprise Edition of harmon.ie, you can also participate in a conversation by either replying to or "like" a post.
