I know getting this fixed is probably not even on the radar, but I just need to vent sometimes! Cart stalls out when editing count of item, EVERY item EVERY time. I must constantly manually reload cart after Etsy "automatically updates" the screen after each line item because it misloads so frequently. This is already on top of it popping me out to the Saved Items list instead of showing the cart after I save an item (pointless) and making you add to cart so you can see how many of something is available (why?!). When you shop at my volume this is seriously cutting into the time I could be paying for more stuff, working on my listings, or creating product. Time is money, and business owner's time doubly so. Etsy needs to consider that kind of cart where you can change the numbers, then refresh after you're done.
Etsy is behind the times wto cart management, item searches both within a store and site wide, and thirdly, fixing glitches in listing format (such as selecting a gem type - you can't change it, you have to start the listing anew!). Recently, all of my new listings have an automatic *digital file* requirement when I do NOT and never have sold digital items. And the worst glitch of all is Etsy constantly crashes during any given work session - repeatedly, daily, hourly. All of these Etsy glitches are a MONSTROUS time sink. Way behind the times, these glitches are costing sellers valuable time and $$.
