The Nautilus location bar presently has a dropdown box where I can choose a view type (Compact, Icon, List).  I think we should replace this with three buttons, one for each view type.  That would make it faster to change views: I could simply click once rather than having to first open the dropdown box and then choose a view type.  It would also arguably be clearer: each button would have an icon visually representing the view type rather than a text name.
