"Reply in new thread" feature?

I don't know whether anyone else would find it useful, but a "reply in new thread" option would be nice for when one wants to follow-up on a post but you don't want to take the original thread off-topic.

At the moment one would have to hit reply, copy the quote to clipboard and then backout the reply, start a new thread and paste the original quote, which is doable, but a little long-winded.

Just a thought, I'll leave it with you. :)
