I know this would be helpful for me but really I think it would help alot of others too.
In the slots for each pet when you go into the all portion of the wishlist page (not the part for a user's personal wishlist) could it be possible to put, like in the items, a FIND button for the pets so have a basic run down of how many of that certain pet a user has and the find option can show them in what groups they are in.
So when a user is going through to add pets to their wishlist they can see exactly how many of that pet they have and exactly what groups they are in. This works for users like me whose goal it is to have a complete CS collection and any duplicates go into my trades, since I'm not intrested in hoarding pets.
It also works for users who do hoard pets and it tells them exactly how many of that pet they have.
One big problem I have is I worry when I do trades that my pets that I want to keep might have gotten dropped in to a trade on accident (I have a slight A.D.D. problem) So I try to be very meticulous about moving pets.
Hopefully this is worth looking into, I know it would help me out greatly! And if this might be difficult to understand please please let me know like I said since I have problems with A.D.D >] my thoughts sort of come out as a jumble...
