Working Branch

Working Branch () on a connected repository card picks which branch the Compute Engine clones. It opens a dropdown of every branch the repository has on GitHub, fetched live through your linked account, so private branches appear only after you log in with GitHub. The next run clones the HEAD of the branch you pick.
