I realize it's actually been live for like nearly 12 hours now, meaning this post that actually recognizes the change comes extreeeeemely late.
But it's here! A new, redesigned nav! (Version History)
We're still tweaking it here and there–including some mobile and touch bugs–and the actual content of some of the submenus may change, I think the team is pretty happy with both the aesthetics and the enhanced functionality the new nav provides. Let us know what you think!
