Generate guides section headers as anchor links to themselves

Hi, I have a suggestion to improve usability of http://guides.rubyonrails.org/

How about making headers to anchors to themselves or other solution like in http://getbootstrap.com/css/#tables (if you hover on header it allows you to copy anchor link)

Yes, there is a ‘table of contents’ at the start of guides, but when you go down it’s just not fun to scroll to the top and finding the exact header you want to pass / share.

What do you think about that?

Sounds great, would you like to work on a patch?
