@ianp5a @FediTips I just read thru your exchange with feditips, which wasn't there yet when I started. I'm still confused 
but maybe getting closer!
so, you're scrolling along down, and at some point you see the last post in an extended thread, of which you haven't previously read the earlier posts? not ideal. you'd like the feed to handle extended threads differently so that you could more easily recognize them and start reading them from the beginning.
maybe?
@ianp5a @FediTips you want new posts to appear at the bottom, and then to scroll up to read them?
note: I still don't think I understand, because this seems to contradict your first description, as far as I could understand it. I'm not trying to be difficult -- just trying to understand, and perhaps help others understand too. that said, if you find my questions annoying, feel free to tell me and/or stop trying to answer them. maybe someone else will respond in a more helpful way!
