See this?
All parts of the new top bar has a tooltip, e.g.
But the poor snow flake? Nothing. No tool, no tip.
Can a tooltip be added, to explain to the clueless user what this is all about? Something like "A list of hats you acquired across the network" sounds reasonable. :)
Edit: even in case of new hat(s) there's still no tooltip!
User will just hover helplessly over the number, wondering what's going to happen when clicking it.
