Is your feature request related to a problem? Please describe.
No this is not an issue, just an additional feature that would help a lot.

Describe the solution you'd like
On cancelling tab next to the gold I own, it would be great to see summary of how much gold could be earned in all above auctions.

Describe alternatives you've considered
There are any other alternatives to this issue... only calculating it on your own, but I guess that is what addon should do :)

Thanks! Works perfectly :)
