Currently, when using Thunderbird in threaded view, the subject line for each thread is the subject of the original, root email. I would like to change this so that it is the subject of the most recent email. For example, the following thread

*- Original subject
|--> Re: Original subject
|---> New subject
|----> Re: New subject

when collapsed displays in the inbox as

*- Original subject

whereas I would like it to display as

*- Re: New subject

Despite my best efforts, I cannot find how to change this. Is it possible without editing the source and compiling my own version?
