Great job with the new look on the Wiki! It looks much better and it is much more appealing to work with.
One minor, in the previous version while editing a page tab would highligt the save button. Very convenient with tab, enter to save when I was finished. In the new version though the bitbucket home at top left gets highlighted. Although it follows some kind of standard it's not as useful. (I'd rather save before going to bitbucket.com)
Once again, great job with the new look!
