Forking takes too many steps
It seems to me as if it'd be fine to have "fork" automatically assume I wanted to name the repository the same way, fill that in, and then have the focus on the "Create fork" button. Or, even better: create the fork with sane defaults, then take me to the admin page. A user coming from github made this complaint, and it seems legitimate to me. Hell, to be honest, something similar to the above might be better for making a repository, too; that's an awful lot of settings to give a user trying to just create a repo.
