Perhaps make it where the player can scroll up and down the family tree. Yeah, you can see some of the recently passed on nichlings, but they eventually disappear over time as well. I've found myself wanting to know about my nichlings' ancestors that I forgot, but I can't scroll up the family tree to find them. If this feature was included, there would be no forgetting the ancestors or having to write down the ancestors' traits so you don't forget them. It would make the game more interesting and easy.😀
