Looks pretty neat! One question: why has the article talk page button been hidden in the edit dropdown menu? It isn't particularly related to editing, unlike move, delete, etc.

I notice wikis using article comments still have a dedicated button for these (so space can't be the issue), and the preview versions of the new page header showed a talk button.
