Checklist of creatures/nations

I haven´t seen a similar thread so far, so I decided to make this suggestion. Please delete this if there´s already a thread like this.
In my opinion it would be good if there would be something like a list... a checklist, where you can see, which creatures belong to wich nation, wich ones of those creatures you already own and how many of those. It would get you a better overview.

I don't need this but it will be helpfull i think :3

Well, it´s just that I´m this kind of human who like to have an overview. Plus we know, how many creatures are still "missing".

Yea, i'm more the kind of person who always has a mess :/

I fully support this idea.
I am one of those people that keeps everything organized and wants to know where everything is and how much progress I've made. I have been keeping something like this in my journal, but it's getting harder and harder to remember to mark things that I get or need.

Yeah, it´s hard to keep track of what is already there, what you´re missing and where you find this.
