I just have a suggested improvement with regards to gifting NOOK books. My wife recently received a gifted book. Thinking it would automatically show up in her library, she deleted the gift email, which I later found out contains the only location with a claim link.
I'm not sure what the behind-the-scenes process is behind claming gifts, but it would be nice if when a user logs into their B&N account if they saw some kind of notification or alert that they have unclaimed gifts pending, just in case they do something like my wife did and delete the confirmation email without reading it fully. And yes, it goes without saying that she could have just read the email.
