Having become a relatively recent convert to a dual screen set up I think a useful feature would be the ability to drag one view of your current project to one screen while having the main view in the work space of the primary screen. If this has been talked about before I would be glad to see what others have said.
the workspace does not float outside the application unfortunately - so, in order to pull of what you are saying you would need to extend or drag the xara program across both monitors. Then, you can use "new view" to create two views of the same project (at different zoom levels if desired).
I would be interested if others have done something different / better.
