So i was fixing to use my hpp on a horse thats on my retirement...well i have tons of horses and have to scroll through all of them to find the one horse several times....itd be nice if there could be a type in ID function on that and even using the cash shop items like retirement breedings would be nice to have a type in ID

Yesss. I like this idea.

what about just changing the name to add a symbol to make them appear at the top?

That's what I've done for my retirement on the "move animals to another of your accounts" feature...
