I just recently switched from using thunderbird to using
sylpheed-claws, because I found this and a few other behaviors of
thunderbird to not be to my liking. But actually in the process of
migrating stuff from thunderbird to sylpheed-claws, I found the option
to stop thunderbird from threading by subject:
Edit->Preferences->Config Editor, Filter "thread", and change
mail.strict_threading from false to true.  Or at least, that's SUPPOSED
to do it, but like the options to not put the graphical bar by quoted
parts of an email, doesn't actually do anything (at least for me)...

Hope it works for you,
