it would be nice to be able to arrange our pets how we want, instead of by age. for example many people (like me) have a "mascots" and/or "favorites" pet group and it would be useful if you could arrange them how you want.
example: you have pets ordered like this due to age
but you think white cat and blue cat should be next to each other, with my idea you could do that
also it would be nice to add short collapsible descriptions to your pet groups so people can understand the group better (ex:adoption center rules or reason for the group) you could also add links to full adoption rules or whatever you need links to.
example: "this is my "mascots" group, i put my favorite pets here to use in dressup scenes and stuff"
