But it could be a bit more nuanced--as long as the cursor is still on the
screen, then shift the view down so that the new recording can be seen at
the top. If the cursor is on the last item in the list then the new items
could go on top, out of view, as they do now. I think that's how it used to
work in older versions (at least I know new recordings were immediately
visible at the top of the list; not sure what the cursor did).
