The billing page has a list of all invoices attached to my account, which shows the date and amount, and number. However, I have to download the PDF to check the status of the invoice. This causes me pain since I have multiple invoices at various due/past-due/paid states and it's difficult to filter out which ones I care about.
When I view the invoices billing page, I am typically visiting the page to locate open invoices that require action on my part, but as is, the page does not make it clear what action is required on my part.
