I've been using Enhanced Steam for a while and it's great; I really appreciate your work.
I'm currently listing a large number of cards in the marketplace and I'm thinking the "My Active Listings" page could benefit from some Enhanced Steam magic. Currently, the page lists the item, listing date, listing price and a remove button. I need to click the individual item to see whether the price on the listing is outdated or not. If so, I need to click "Remove," go back to the inventory, find the item, and list it for a new price, which may involve having to click the item again to see the current listing prices.
I would love to see the following: A column that lists the lowest selling price and perhaps the last sale price, so I can see at a glance whether the item pricing has changed significantly since listing it. This could further benefit from the number of items listed at the lowest selling price. Finally, the addition of a "Re-list" button which would remove the item and present the item sell dialog would streamline the process and negate the need to return to inventory, find the item and then have to list the item from there. This would make managing the items I'm selling a much less labor and time intensive process.
I would imagine that many users that have enjoyed the fruits of your recent efforts would benefit from enhancing this process.
Keep up the great work!
