Having recently migrated to XF myself and the members are experiencing issues with last unread. From feedback and personal experience this is what we have found: Create a new thread, make some posts, others members post, if you go back to the thread as long as there is an unread post it takes you to it. If you then go read other stuff and then decide to go back to a thread you had previously viewed by clicking the thread title it displays the first post and there is no "goto first unread" button. Are we missing something here? We are finding it extremely frustrating having to click a thread title, then click the last page number and then scroll all the way down to the last post. I know I can click the time under the last poster to get to the last post but everyone is used to being able to click the thread title and being sent to the last position regardless of new posts.
