I originally removed the secondary nav but realized it is really handy on mobile. Otherwise the main nav is collapsed so this offers handy navigation on mobile!
What's New's sub-nav options are replicated below (unless you have official add-ons), and that was my gripe as it is redundant, but the other selections are not exact replicas. I considered hiding it only on the What's New main page but I decided to leave it for continuity.
It has proven to be a good tool!
