Updates for 4.0.1: The price-each functionality is working and the AH frame is movable; however, it can't yet remember prices or auction durations.
qAHImproved is a very small addon, operating fine with or without Auctioneer, to provide the following AH Improvements:
1. Adds a column to the Browse view, showing the price each for both buyout and bid prices
2. Adds a button to sort the Browse view by either Bid or Buyout price (NOT Functioning in Wow 4.0.1)
3. Remembers the prices of items you've auctioned before (FIXED)
4. Remembers the duration of the last auction you set (FIXED)
5. Makes the AH frame movable
6. Batch posting re-enabled
