I'm not sure if I'm for or against flattening the hierarchy, but here are a couple of points: - Currently, the tabs at the the top level are github-related, and those at the second level are git-related. There is a certain sensibility to this. - Zenhub, which adds a kanban board powered by github issues, adds a tab at the top level, which makes sense according to the above hierarchy. Of course, a third-party browser extension shouldn't be a primary concern if github thinks about redesigning the page.
