1. Performance-Friendly mode that tries to use less CPU for overnight
wolfing runs. As others mentioned, lack of graphics, etc, would be nice, but considering this simulation is largely based off of the physics of the animals and the physical layout of the world itself, there may only be so much you can do.
2. A dedicated full-screen view listing all the species, the amount of members currently alive in each species, perhaps with a map overview showing only the locations of the members of the species selected. From this screen the ability to boost and cull entire species at once, as well as being able to see and move mating zones. I'd also like ratio analytics of the proportion of total foragers to predators to apex predators to understand the overall health of the ecosystem.
3. As someone else mentioned, the ability for species to move up and down the food chain. Specifically, it'd be nice if species randomly mutated their diet type. I had also thought of the idea of specific forager niches, of there being a chance foragers developing specific tastes for specific plants.
