I'd like to see breadcrumbs at the view level so you can quickly go back up 2 or 3 levels or back to a search results page or page X if you're drilling down deep into responses to posts.  Similarly, if you open up a post, it would be nice to have a breadcrumb at the top so you can navigate back up the discussion thread without having to use the back button in the browser, or at least a link back to the topic map for that post.

I guess with XPages we've lost the ability to do "Copy as table" when using the Db in the Notes client.  Is there an alternative?

The breadcrumbs issue is now obsolete because you can see all responses in a thread on one page.

There is currently no alternative to "Copy as table" in Notes when using the Xpages UI in our forums. This is a trade off we made in order to use the Xpages UI in Notes.
