Wow Reagent Vendor

Wow Reagent Vendor

Particular addons for wow?

Hello,
due to a problem with the pc (formatting, data have not saved me T_T) I'm trying to play the "wow" the addons. Have already been the site curse, but I do not remember the name of the addons, nor in what category. It is not that perhaps some of you have quell'addons I need and I can say something more?
Description: When you select (just go over with your mouse, do not click) opens a window in the base where you say as what the item from the vendor, for which the profession can serve the reagent or the skin, if you disenchant the percentage of reagent that can come out if a piece is "special" which tells you exactly ista you have taken so.

Excuse me for bad English, but I am using a translator.
Thank you in advance for your attention and help.

No Problem, you want enchantrix i thinks its called. It comes With Auctioneer .
