If a student clicks in a forum discussion and sees the middle of the discussion in a topic, often he wants to switch to the starting point or to see all posts of the topic.
He can do this by clicking in the breadcrumb navigation. But this is not intuitive. There is a large headline with the title of the forum and the topic. But they are not linked.
It would be much easier for users if they could click on the headlines or a button between the two links to previous or next topic.
