Thread:Feedback/Reply to message and Add Message/Tgr (2)

Maybe subthreads could be hidden by default? That would be a strong disincentive against starting them unnecessarily, and it would also make sense from the reader's point of view if the subthreads are indeed used for tangents and off-topic conversation.

One advantage of the current nesting-rich layout is that if an admin hides a troll comment, all replies will be hidden automatically, which is a disincentive to feed the trolls. It would be nice to preserve this effect if the layout changes.
