I think there is a design flaw with step 9: The code tab has been changed to "overview", but an overview is supposed to be a glance of something, not an authoritative source of data. So where's the authoritative source of files in the repository now? Are we supposed to be using the "overview" as a file browser too? I don't really want to see all that stuff on the right if I'm just trying to traverse some directories to get to a file.

I like all the changes prior to that one though.
