Currently, aside from the island area where you can expand upwards, all areas have a limited viewable space at the top of the screen (that you can't build/place objects on). The viewable area is fine usually except for when you want to place your Wonders around the top of the screen, the Wonder (specifically the really tall ones like trees/mountain/springs etc.) gets cut off from view so it's not really a good option to place them at the top due to this limitation.
Personally, it feels like such a waste to not be able to appreciate looking at the full view of the Wonders since I feel some of them look better being placed at the top of the area at times.
It would be great if the viewable (but not buildable) area at the top can get increased a little, like adding more viewable sky or something to at least accomodate the height of the really tall Wonders. I think it would be a great addition for decorators who want to have a bit more flexibility to place their wonders.
Just a few examples of stuff getting cut off due to limited viewable area:
