I like the new Bitbucket new pull request experience. However, I am not finding a good way to navigate the sidebar when the file list goes off the bottom or when there are many comments in the activity list. I've tried resizing the side bar, hoping a scroll bar would appear but it doesn't. Sometimes I can click in the bar and then page up/down to jump navigate, then cursor up and down, but that doesn't consistently work. What am I missing? I'm using Chrome in Windows 7.
