Also, clearly the clients are still new. I'm trying out Connect and Liftoff. Connect didn't indicate anywhere obvious that I had a reply and has no button I can find to reply to replies. Liftoff handled both of those better, but it also hid your reply at one point and I had to use Connect to make sure it still existed. Neither client has a button for seeing reply parents, so to be honest I do not remember the comment you replied to and have no easy way to find and read it.
