Oooh, that does look nice, apart from being long-abandoned.
The other thing I want, which is quite idiosyncratic perhaps:
I use my bank to store extras -- I usually only list one of most non-stackable items at once. I would love to have a quick sanity check of:
* Is anything in my bags already listed?
* Is anything in my bank neither in my bags nor already listed?
This would help me run my auctions efficiently.
