On the bitbucket.org interface for a repository:
there was previously an easily accessible "fork" button on the left-hand-side menu to fork the repository you were looking at. The "fork" functionality has now been moved under the "Create" button. This is really not intuitive and it took me ages to find the new location. I didn't even think of clicking "create" because I didn't want to "create" something new; I wanted to "fork" (copy) something that already existed. Could the fork button please be put back directly on the left-hand-side menu rather than in a sub-menu?
