Here is a simple time saver that is commonly overlooked. I love the way the product pages work on most of our sites with the bread crumb trail at the top so that you can easily go back to sub category or category pages. That would be a great addition to the product editing pages. Without it I find myself constantly searching for subcat's or category pages or even worse hitting the back button ten times to get back to where I could easily get with one click of I had the crumb trail.
