Lagoons and aviaries can get quite large in the game. The normal viewing galleries don't always reach far enough. It would be nice if the viewing platforms could snap to the lagoons and aviaries. They would need some slight remodelling to fit properly. But especially or the aviary it would give a nice alternative higher view from inside the dome. For the lagoons isn't not that big a problem right now, since we can place viewing platforms next to it and still look at the lagoon. But this doesn't work for the aviaries since the dome is in the line of sight.
