I do not use that feature very often, and Yahoo's way of doing it (recently pushed at us as a default) is awful, though globally toggle-able.
However I DID notice that in ZOHO (which I have been evaluating since August), you can do exactly what was suggested here, with an icon being offered next to any post which the system notices is a candidate, and when you click on it, that post alone will open into threaded view.
