Add table of contents

[rodarima]

It would be handy to have Dillo automatically create a table of contents based on the document headers. This would also allow jumping to a given header which doesn't have any anchor link, but it does have a unique id.

This would also allow a new entry in the context menu to copy a link to the current section (or element).

Even without trying I can tell that this would be a really good feature! I would even go so far as to add an option to have a fixed sidebar or top bar that would show me this toc constantly. That is.. if dillo is able to have a part of a page to stay on fixed position while another part is being scrolled. I could then quickly jump from one header to another on the page without needing to use scrolling so much. I vote for highest possible priority on implementing this one :)
