i'm not sure if others are just more organized with auctions than i am, but when i post something for auction, in addition to the lowest price, i'd also like to see if i have any of this item already up and for how much. going through my list of existing auctions in a new tab each time is a pain esp when it's multiple pages.
particularly for musicblocks - if i already have 3 of some kind up, i usually don't add any more until those have sold. i also sometimes accidentally underbid myself when i'm not one of the lowest three shown and i'd like my prices to be consistent. (and not accidentally drag down the prices for everyone.)
