They look huge at the moment - I could understand if they offered a live preview (even though they'd be still overly large), but at the moment it's just an icon with a lot of white space!
So I'm using Home in production now and I really really like it. But these massive icons are soooooooooooooooooooooooooooo annoying when you click on something to view a status update and have to scroll past these HUGE previews. (If they weren't so big it would actually be super useful to have the documents be shown!)
Can you please do at least one of the following:
1) Make the document icon previews smaller
2) Allow an option to show only document name (i.e. without an icon)
