Isn't working correctly anymore :(
Auctionshousewindow is lagging with this addon :(
Edit1: Shift-right click on the Buy Out button works fine. Auctioneer Advanced doesn't play well with others, so shift-right click on the individual items doesn't work with Auctioneer Advanced running.
Edit2: It works fine without Auctioneer running. Other addons may interfere as well.
