Auction House Revamp or AuctionFaster Addon Backport

With the AH plagued of items stacked in 1's, especially in Frostmourne, I think it's time that Warmane copies the AH revamp from retail WoW. Frostmourne already introduced mythic dungeons anyway so an AH revamp wouldn't be killing the classic vibe as it's already dead. Also wouldn't mind if the AH revamp is for Frostmourne only.

If this isn't possible or if it's too hard to do, then can someone please backport AuctionFaster addon from patch 8.2.5 before the AH revamp? This addon directly gives you the cheapest searched item (without scanning the pages like Auctionator) and you can find the x amount of stacks you want.

For example, you want to buy Frostweave Cloth by stacks of 20 only, you can then click on the 'Find X Stacks' button and input 20 so you can see the cheapest Frostweave Cloth that's listed at stacks of 20. And no to mention that this addon is very LIGHTWEIGHT.
