In GS6 on the right sidebar, we were able to see all the previous times an item had been listed, thereby giving us the ability at a glance to decide if an item needed to be reviewed for a pricing change or other adjustments. That feature disappeared in GS7.
Also, there does not appear to be a way to view the sales info from within the original listing. Pretty certain that used to be part of the same area in the sidebar in GS6. Just today, I looked up a listing, and was curious whom purchased it and what the final sale price was, but was unable to find it. The sales data is no longer kept as part of the original listing, nor am I able to search by item title in the Orders tab.
