So I think it could be a really neat feature to have a sort of.... Breeding Journal, for players to update and modify. Just a plain family history style sheet, with spaces where breeders could either input a specific pet, or a list of traits, so they can follow down what their breeding project is. It could be like the Pet Generators, where you have a specific number of "slots" you can save for different projects, but you can load them up so you can modify them as your project progresses. You could have it to where it's private and only you can see it, or you can let others see it like the designs on the generator.

It would be an easy, on site list for breeders to manage their projects and keep an eye on what they were even planning, because I know I've forgotten some of the original breeding goals I had. :P Just a thought.

Lots of support! This would be very helpful. For now I use docs and it's a nightmare...

This is actually a really great idea and has my support.
*I'm guilty of using one of those family tree apps meant for the sims 4 just to organize my projects*

I 100 percent agree with this. It's hard to remember the pets to breed together and then I forget and breed a baby I didn't want. And using like google docs or something like that would be a nightmare so I think you're on to something! maybe one of the Moderators or admins will see this and make it happen!
Or like 12 plans per species
ex 12 Puffadore plans 12 'Nixi plans 12 'rikki plans ect.

If you see this admins or mods. ect. please make it happen!
It would be super helpful for the breeders of Sylestia!
