It makes no sense to me that the auction house in the game itself is not nearly as user friendly or as quick as the auction house in the companion app. That's absolutely absurd.
The auction house in the game itself should keep a history of your searches. You should be able to save searches. You should be able to quick search. You should be able to pin things the same way you do in the app. It's unexcusable that the game itself is not as user friendly as a stupid companion app
