Provide a record where clients can view all details of their gift codes, including the date they were generated.

As someone who's been having this problem very recently, I second this 100%! (Especially as I was completely unaware of the fact that there WERE any gift codes barring a couple of isolated promotions...maybe OBC could make that clearer?)
I would also like for authors to have a little more control over when those gift codes get offered up (maybe a "Release 10 codes" button to make an official request?) I was recently informed that over 500 for one book had all been redeemed at once. Given that people tend to read at similar speeds, this means that my inbox is likely to explode with notifications of published reviews and potential errors at some point, and I'm really not looking forward to it.
