Pet categoriee are automativally srt to alphabetical order. Some people name their pet groups A. Dogs B. Cats C. Horses etc. to get their desired order. I also remember reading that there's a way to use spaces at the beginning of a pet group to manipulate the alphabetical order, but I'm not sure how to do it as I don't use that method myself.
I believe pet subgroups are a feature in the works, but currently there's no way to do this.
would anyone have a tutorial or format that they use for organization? i wanna be able to have like a "folder" for each species in a tradeable section, and then the same in a non trading section
