We have a Whats New that works extremely well. But no Todays Posts or Latest Posts?
In case we want to get back to a previously read thread with more information, and chronology (when the last post was made) is the only thing we remember.
The "what's new" link already shows what I would consider to be "latest posts." It has a separator between new threads since your last visit (inactivity read markers) and unread threads which are still unread since before your last visit (persistent read markers).
If this is what you are after, reverse chronologically listed threads - both read, and unread, then in Whats New there is a link that on the right hand side called 'All recent activity' now.
