This is NOT an improvement.  Our invoice list is very long.  It was much more useful when I could click on the invoice from the Customer tab and see it's status and activity at the bottom.  This new method is essentially useless when looking for the status of an older invoice.  Even a couple of days renders it almost impossible to find in this manner.  Perhaps if you the "upgrade" department focused on request upgrades instead of fixing things that aren't broken without a really understanding of how they are currently beings used, we'd all get a lot more done.
