I see a couple of posts about this but am unsure where things are: is there a setting such that as new posts arrive and I look through them, I only see unread posts? I mean, even when moving to next unread with the space bar. So far, what I've found is that I can Hide Unread, but then, spacebarring along through these then I see all the read items in that thread too. This is how it works in Thoth, and it suits me very well as I'm not normally interested in seeing the entirety of a thread. Occasionally I want to refer back and then I can.
