In the grand scheme of things, this isn't a big deal… but it's one of those little details that should be taken care of at some point. When you use the find window in the PBB tool, once you filter to no results, the "You haven't made any personal books yet." message appears. This isn't helpful. [:P]
What WOULD be helpful for some users is a message notifying them that they have filtered the PBB tool and a suggestion that they try again.
