My main dislike is a technical feature: that every response to a comment does not link back to the parent comment. This often makes discussions difficult to follow. (Indentation helps very little when reponse threads grow over multiple pages.)

  that every response to a comment does not link back to the parent comment

But it does, unless I misunderstand. Clicking on the time-ago link gets you to both the Parent (of that comment) and on: (top of comment thread for the submission overall) links.

What I do in this case is to close the tree (-) when reaching a comment less indented, so I can continue the current responses and remember where I was.

Not ideal, but it helps me.
