Wow this is a slick user interface!
I wonder if we might be able to post something technical to our blog about the various iterations of the new look and feel. It was a massive difference along the way. I'm going to suggest this to the team because I think some, like you, might really like to see how it evolved as development progressed.
I'm definitely going to let our designers know about your comment though. They had their work cut out for them on this release.
More fun though is some of this makes a lot of sense to bring to 1Password for iOS.... hint hint...
