Sorry i didnt know where else to post this, was wondering if someone could help me. I have two screenies of the addon circled in red, Ive gone through all of them and cant find what it is, so I was wondering if someone could tell me the name of the addon. As in the one screenshot, and most often, it gets in the way of things, especially in the AH, and I cant read stats on items and such.
While he may have Informant installed and active, Informant is just an OptDep for Auctioneer, not a ReqDep. As was already cited, EnhTooltip is the ReqDep for Auctioneer.
As for configuring it, I'm not sure about the latest version of Auctioneer, but it used to be hidden away in the auctioneer command line options (/auctioneer). You had some moderate controls over it, like being about to merge it into the main tooltip, rather than having it as a child tooltip, or being able to govern what information you wanted to display there.
