make it useable
horrible layout and use of screen space. Looks clumsy and messy. Chats not organized. Things are all over the place. Files opens sharepoint. Notes opens one note. its a frankenstein. Looks dated and cluncky. Things are slow. In a nutshell, a big turn off. Please dont force this on us.
