@drq @mo @BigFoxBoss ok, as you want you answer show multiple times, this could be rendered as reply, but with link to another thread point with first reply source, instead of rendering all children. That duplication will allow keep consistency and even work with "polytree" model.
But in that case only one reply source will be rendered, other only referenced
And this will not show single thread as "Polytree", there will be 2 separate threads, but with "weak" junction point, so all next replies will go to thread, where first reply source was
