If I was to click on one of the recipes, it shows only that recipe.
That's not correct. If you click on an item in the auction, it will show all listings for that item. If you click on a 'moonstone cloak recipe', only moonstone cloak recipes will be shown, not heavy cloaks or anything else. If you are only seeing one, that is because there is only one for sale in the auction at that moment.
That being said, I am starting to agree with Radoo in wanting more ways to view/sort recipes in the auction.
It would be helpful to have the
option to view only the recipes I don't already know. That would shorten the list down dramatically. Two radio buttons that allow me to 'view all' or 'view new' recipes. Should be simple to implement...?
