Sorry, I don't.
I agree with your suggestion of keeping windows open for the latest posts in various forums. I don't think I'd want a Super Latest Posts page; I like the idea of separate forums separating the news from the fluff; just wish it were better enforced. I do understand that sometimes there is a fine line.
It would be nice if the pager worked across forums; I have missed posts to me in forums other than News/Activism for longer than I'd have liked.
In my opinion, (and I know some people will disagree), prayer threads, ongoing daily chat threads, Laci Peterson/Kobe Bryant/Michael Jackson threads and a few others would be better sent to chat -- I'd rather see just news of national and international import (and opinion columns about the same) in the News/Activism forum.
