I know this isn't on any priority lists, but when you get to doing the battle stuff, it would be REALLY useful if when you go to a pet's statistics page, if it linked to the start a battle with the opponent page when you click on the names. Even better if it could filter by available opponents (so seasonal ones could be filtered out), difficulty level, and number of wins. I find it really helpful when I want to battle for EXP to raid that list, but it's not always easy to find where the opponents are hiding.
