This would mainly be of use to people that use mailing lists. Some of the time 
people start a new thread by replying to an existing post, rather than 
starting a new one. This then shows up in thunderbird as a reply to the 
original, as opposed to being in it's own thread.

The ability to be able to select a message to break/split the thread so that 
the selected message is no longer displayed as part of the original thread, 
but at the top of it's own would be useful.

What's even worse than mailing lists is when someone sends you messages with the
same common subject, for instance "FYI" or even "" (no subject). I have about 5
of each in my inbox right now, and none of them are related.

I think converse action of this is important, too. I often want to merge
threads. I submitted bug 295873. I guess that makes it "half-duplicate".

I have also been bugged (no pun intended) by this for a long time.
I have just uploaded my entire archive of e-mail to GMail, and I have one thread in there with subject "" that spans hundreds of unrelated people, and almost five years, that in fact _is_ unrelated!

If I may make a suggestion:
From my observations, TB threads the mails based on two criteria (remember, this is only MY observations, and may not reflect reality): based on the References or possibly In-Reply-To headers and the Subject. If I am correct, then ideal solution for me would be to create a boolean Preference (in the prefs.js), something like ignore.subject.threading that I could set to false, after which mail would only be threaded if it contains the correct References or possibly In-Reply-To headers.
I swear there's another bug on this.

In the meantime, confirming this enhancement.

This request is about splitting, the one marked as the duplicate is about merging threads. It's a similar topic but not a duplicate.
