The Auction house mod

How do you get that mod i see lots of people having that can someone tell me how ?

Well, can you describe what it is? Like some pictures or some other stuff

its basicaly a mod that show's you more info in the AH, as in a live count down for how long the item has left. info of the person who is selling that item, and it can arange things around a bit better, also refreshes quicker. i've seen vids my self but never tried downloading it, didn't see the point
