> Yes, but it's much more cumbersome to navigate the thread compared to using an actual mail client. If web pages of mail archives could present an overview pane for navigating messages, it would go a long way to making them usable in a browser as opposed to just posting links to the immediate parent and the set of children for a given message. It does, although discovery of the feature as well as the feature itself could use some improvement. In the header there's "Thread:" and the associated button displays the structure. You can also open a whole thread, but I don't find that particularly useful. The download mbox link inside a message will give you the whole thread as well.
