It's quite limiting having the object user interface the size it is. Of course you can just move onto another page but it would make it so much easier and user friendly to be able to include more on a single interface page. You can adjust the size of MVO pages so I can't see why it wouldn't be possible for Graphisoft to implement it for object interfaces.
I just had a look at this. It kind of works however you are able to shrink the Object Default Settings window to cut out anything that is outside of the standard x and y
