Let's use ?status=closed and ?status=open

?status=closed and ?status=open at the end of URL can be used to show only open or only closed topics within Latest, New, Unread, Top, and while viewing any category (doesn’t seem to work with the list of categories that shows latest aside it nor with viewing by tag).

We can edit the nav links so that Latest or Top or whatever default to hiding closed topics. Or we could have at least one nav link that does that, perhaps in addition to others.

It seems ideal if this were a drop-down or something that could be adjusted for any view, but that probably isn’t something we can easily set up.
