What is the enhancement in mind? How should it look and feel?

Not sure if its possible to do, or maybe some addon already does it but here goes.

I usually list huge amounts of auctions at the same time, making the list in the auctions tab very long and hard to get a good overview of. What i would love to see is an option to add a small total at the bottom of the frame below the listing (or at the top) that shows the total value of all auctions i currently have posted.

Item #1 Bid:1g BO:2g
Item #2 Bid:1g BO:2g
Item #3 Bid:1g BO:2g
Item #4 Bid:1g BO:2g
Item #5 Bid:1g BO:2g
Item #6 Bid:1g BO:2g
Item #199 Bid:1g BO:2g
------------------------------
Totals: Bid:199g BO:398g

To give a better overview as to the value of active auctions.
