The new layout of the repo screen is decent, but the new, overly-smooth UI components are too much of a departure from the previous, well-done UI components.

The way the top tab/nav bar stretches across the screen, while the content is centered feels broken to me.

(above) I mocked up what the repo screen could look like if it used Github's previous UI with the new layout (and fixed the fluid tab bar!)
