Guests' viewing range: Like in Jurassic World: Evolution, an option to see where guests can see the animals from and to what range they can see them in the Analysis View Mode can be a great option to know if your animals will get a better sighting than "ok... I guess?"
Burrowing Animals: In my Zoo Tycoon 2 days (which are ongoing), you were always challenged to select suitable barriers for animals that can burrow underneath them (like meerkats). This can also create a new type of challenge to handle in Planet Zoo.
Building ON roads: This is a big issue for when you want to create a plaza. Especially if it's one on an elevated platform.
Extra Suggestion: Challenges that can reward animals (or something other than cash).
I don't expect changes like these to come soon as the game is still in its toddler stage (which is great so far, by the way!), but it would be nice if something like this could be implemented in the near future.
