OK, that's a pity.

It's only for three newsgroups and only for occasional articles so a
manual command would be better than nothing.  If I use "pipe
article/thread/hot/pattern/tagged articles into command" in tin and
output the result to the window where tin is running will I then be
able to return to tin afterwards?  I'm often doing this via ssh so
popping up a new window for display is not so easy.

Yes, though the trouble is partly that it's very difficult to see
what's in the article before I decide to reply to it when it has the
[quote].....[/quote] in it because they don't stand out at all and, of
course, there's no differential colouring.

OK, I don't think I'm quite that desperate though.  :-)
