my wishlist for HN is toggle-able lines up to connect thread parents / GP, etc - kind of how notepad++ highlights the parent DIV.. thing is I get a few page scrolls down into threaded comments and find that I am not going to read all the back and forth holy war on one particular nit.. but I want to scroll rest of page to see if other topics are brought up - but it's easy to get lost on the up and down scroll and just give up trying to sort where the forks in the road went off the rails. Maybe this or something else mentioned here does this - not sure.
