A timer would be pretty pointless imo, but what do you mean by "an overview of current generation"?
When i think of an "overview of current generation", i mean that you can zoom out with the camera and also move the camera with the arrow keys. And like i said in the post of the walking human (https://itch.io/t/228740/did-anyone-get-a-good-running-humanoid-creature), i "train" my creatures in a special way and for this would a timer be very practicle.
