Describe the solution you'd like
After solving NET there is an expanding circle of color animation that ends. The networks that are generated by the game are fascinating and I'd like an additional feature. Once the game is completed, change the energized color (presently blue) on one of the outputs at a time - this will highlight each network in turn. I guess an option to enable/disable the additional animation would be nice for people that might hate it or have sensitivity to flashing lights.
