I've been looking for this for some time in some form or another, but have not found anything like it in auctioneer. It would be great if auctioneer allowed you to easily input the names, drag and drop, shift click, or what not certain items you want to keep tabs on then allow you to run a search and compare all the results at the same time.
Right now you can only do this with general searches and WoW itself does not support more then one search at the same time. IE dreaming glory; fel lotus and it would bring up both of them at the same time.
Why would you want to do this? It would save tons and tons of time if you frequently search for more then one thing at the auctionhouse (most people do).
there's nothing we can do with the WoW search unless they add additional functionality. we could conceivably add it to our snapshot search though - feel free to add a JIRA enhancement request for it.
You can probably use snatch combined with bottom-scanner as a stopgap in the mean-time, if you have an idea of what you are willing to pay for the items.
