'Mark as read' needed within categories

If you “cleared” stuff off, do you want Discourse to remember your position in the topic when you eventually re-visit it? Or do you want discourse to skip all the posts you did not visit?

In the equivalent feature in Gmail, if you mark a thread as read and then open it, all of those messages are collapsed. That seems analogous to skipping all the posts in a discourse topic if the feature were to exist here.
