If your newsgroup software can support this, I'd like to see the
« Previous Thread | Next Thread » links added somewhere at the top of
each thread page.
Sometimes it takes a while to load a page and I have to wait
till the « Previous Thread | Next Thread » links become available
to click on at the bottom of the page.
I'm not suggesting moving the current location just see if you
can add the same function to the top of the screen somewhere.
