Currently, invoices are sorted with the oldest on top. I've been subscribed for a while now, so I have to scroll to the bottom every month to see the latest invoice.

While you are at it, removing empty ($0) months and indicating Paid vs. Upcoming in the list would be helpful too. Also, returning to the invoice list always puts you at the top, which is never where I want to be. Please remember my place on the list and return there.
