Title says it all, please sort the different items alphabetically.
Better yet, add a couple of columns to show school and level (like at the bazaar) and allow sorting by those as well. Also include the crowns or crafted icons on the proper items.
Another thing to consider is to include a way to filter out items. Like a list of a few options with the choice of yes/no (and if neither or both options are checked, it shows items matching). Tradeable (yes/no), Auctionable, Sellable. If someone checks the 'yes' option for tradeable, then only tradeable items will be listed. Also provide a list of schools to filter with.
