I added the bookmarks, so they can be used as before.
Also, "Read new messages since my last visit" is not going to be added to the new board. It's broken here (misses messages) so replicating it doesn't make sense.
Instead, the Recent Topics list will only show the topics that you haven't seen. And when a topic that you've seen gets a new post, then it re-appears there. So you can use the Recent Topics listing to catch up on all new topics and all updated topics.
You can also pick which sections to filter from the Recent Topics list. It's in My Profile (at the bottom). So you can exclude the sections that you don't want appearing there.
