My most actively-used pieces of information when selling are:
-Sold, Active listings, Unsold, (left-hand side), "selling reminders" (middle page) and "messages." What is missing from this is a one-click SEARCH mechanism. People aren't all gifted with the ability to remember the specifics of hundreds of listed items. If I want to SEE a specific listing, there is NO WAY to FIND it in the page shown below. I've seen the "Seller Hub" which has a search bar (the old version anyway) but the Seller Hub is not as easy or fast to navigate as what is shown below.
