Lots of good suggestions in this thread. 🙂 

My wish list remains pretty much the same (though I did get the out of stock control feature 😄 ) - at the top of which amounts to eBay enforcing their buyer policies, most specifically the one relating to using other IDs to buy when any one of them has been blocked by a seller.

Plus, clarfication on a wide range of issues the MBG has since introduced, along with another overhaul of the "new and improved" cancellation process so that it actually works properly and sellers aren't left waiting for 10 days after a buyer requests a cancellation then doesn't know what to do because they're being asked to confirm a refund on an item they never paid for.

If they won't remove the ETA in listings, the least they can do is make it clear it's not a "due date", and they're just guessing on behalf of sellers and postal services. 

It's unlikely eBay will ever allow a minimum spend feature, but you can do the next best thing and use promotional postage rules to set it up so that postage is free when a certain $ value is reached. It can work in conjunction with other postage rules (eg say you have $5 post with each additional item @ $1 post, then free post when the order value is $50 or more). Eventually the item price discounts feature should be rolled out to all sellers. I know neither option is as good, because it means you have to price items higher on average from the outset, which tends to = lower interest etc from search results and the like, so it would be kinda nice if this new feature they've got highlighting markdowns and postage deals on listings was also reflected in some way in search results (without having to pay for a subtitle 😄 ).
