There are a few things I would like to see added to lists, navigation, and shipping computations:
1) "Listing's I'm Running": Most important on this list is to show the shipping fee, "free", or "calc". This way, when the USPS increases their rates, it would be much easier to determine which listing need to be updated with the current rate. As it is now, you have to open every stinking listing to see which ones may need to be updated. Without having that, it took me several weeks to review and update all my listings.
2) For a potential buyers: When looking at a list of items, I would like that list to show the shipping rate for their location (assuming they are logged in) rather than "calculate" as I believe many potential buyers skip over the listing that show "calculate". And, many others get sticker shock when they actually enter listing details to discover what shipping is which skews the view count with those who aren't really interested in the item. Lack of this feature forces me to use "flat-same cost to all" rather than "Compute" which then results in needing to edit items every time USPS increases their pricing just to make it easier for potential buyers to quickly determine the cost of an item. And, for rates that aren't zone dependent, this could be done once at time of item entry/change and again once after any USPS price change to have a price to show without doing commutations every time for these items.
3) During editing an item, I would like to see addition of a "Cancel changes" box which returns you to the previous window.
4) After editing an item, I would like to see a "make another change to this item's listing" click spot. As it is now, I have to go back to long list of my items and search for it to make a change that I realize I missed after saving my changes.
5) After editing an item, I would like to see a click spot which returns you to the item page you were on before you edited the box. As it is now, you have to return to full list then enter search parameter to find that list of items again (I just did that a ton of times last night to correct about 90 listings).
6) When using "List Similar", I would like an optional setting to my profile that would tell the editing to drop photo from any item to force me to choose correct photo for the new item.
7) When using "List Similar, I would like an optional setting to my profile that would tell editing to set item count to 1. There have been many times when I've used "List Similar" but overlooked changing the item count. I'm much rather have it at 1 rather than risk selling more than I have.
8) Shipping computation: I would like the ability to add a fraction of an ounce. Having 1 oz increments makes it impossible for the freight rate computation to compute the correct price for light weight items.
9) Ability to enter a larger quantity such as having 1726 in stock.
10) Shipping Computations: Add USPS Priority Mail Regional Rate boxes to list of available packaging options. For smaller heavy items, these are great. I've used the Regional Rate A box to ship many items but can't charge correct postage for it. For instance, my last shipping in one was a 4 pound item with shipping rate similar to that for a 2 pound item when in this box.
11) Shipping Computations: Addition of feature to take size of an item into account when computing shipping. While many larger items may be able to be shipped together in a single box at a lower cost than separate boxes, packing them together could require a larger box which would in turn invoke USPS "Large Package" pricing fee which is not currently taken into account.
12) The ability to select and show more than one notice for an item, group of items, or store. Plus ability to indicate whether this should be shown before or after description of the item. And, allow more characters in that notice than is possible with current notices which only allow one to be shown with not enough characters allowed in it to say what you need. As it is now, this info must be typed into description of every item it's applicable to which then requires editing each of those items any time you want to change this wording.
