Auctionator is designed for casual everyday auction house users. Auctionator makes the auction house easier to use, by presenting auction house listings clearly and succinctly, and by eliminating the tedium involved in posting and managing auctions.

• Auction prices in your item tooltips so you can quickly see how valuable the item is that you just picked up
• Adds the Selling tab to post items quickly and avoid underpricing.
• Adds the Shopping tab to search and filter for multiple items at once
• And adds the Cancelling tab that lets you cancel auctions in one click and scan for undercuts.
