As Blizzard removed pet count cap, it would be usable to have a search option to filter for a pets not fully collected 3/3. Sometimes really expensive pets could drop in price which allows us to buy them and sell later. Let's say I wish to include in search all of the pets which I don't have and I have 1/3 and 2/3 but hide the ones collected 3/3.
At the moment if I check "Include collected pets" checkbox, I get all of them which is the same default auction search already does.

Thank you.

I've put a version of this into the latest alpha

I tested new alpha for a few days now and it's working just fine. Thanks you for improvement.
