I'd like to have a simple addon that would enable you to sort auctions by buyout price and not only by current bid. Back in the days there was an add-on that did the job ( AuctionSort ) but since 2.3 it has been giving me tons of errors.
Any chance someone has some free time - I only got ideas, no LUA skills :]
What would maybe also be interesting is a feature to sort by cheapest "per piece" price. If for example you want to buy Mark of Sargeras or Sunfury Signets there are usually a lot of them on the auction house but the quantities are really random. It would be great if you could easily sort by cheapest "per piece" buyout to get the best bargains without having to manually check several times.
A very positive side effect would be that the scam where people put a single netherweave cloth instead of a whole stack on the auction house would be easily prevented because those would get sorted to the bottom by that method :)
