I have one big argument against having multiple graphics view: One of 
the benefit we can get from using graphics view is the use of openGL for 
3D transforms, transitions and animation (via WebKit's accelerated 
compositing), and for WebGL.

This mean the graphics view's viewport would be a QGLWidget, so it would 
have a GL context. If we have more than one view per window, we would 
end up with plenty of GL context, and GL drivers do not really like that 
kind of mess :)


Having one graphics view would enable a few fancy stuff as well. For 
example, when passing from one tab to the next (ctrl+tab for example), 
we could scroll the view to show the next page. This scroll could be 
animated so we see a visual transition between the tabs.

Another fancy thing possible is a "exposé" mode for a window. We could 
add an icon to the tabbar to show all the open tab in a single view.

cheers,
Benjamin
