Is there an addon that can just save my common searches so I can say, click a button to search for a Carnelian or Embersilk Cloth rather than having to type it every single time? I don't want all that scanning crap, just the ability to save a list of bookmarks.
No idea, it's perfect for the job so I never bothered to look.
Edit: Auctionator (that I use) and probably other popular Auction House addons also let's you save searches,
but they also have alot of other functionality.
My reply was for a standalone addon that does only what you asked for.
