I love tabs. When I have a section with multiple subtopics (what I would have used H3s for if not for tabs being better visually), I use tabs to reduce the scroll length of the article and help with organization. However, I don't want users to miss the content. Ideally, I'd love to be able to make tab titles H3s or H4s, so I can add them to the table of contents. Also ideally, when a user clicks on a tab's link from the table of contents (if it's not the first tab in the list), the article should auto-scroll to the tabs and open the clicked-on tab.
