Maybe I am misunderstanding it’s purpose, then. So it is an indication ONLY if the last person to reply was the topic author, not as an indication as to WHO the last person to reply was. Is that right?\
IE, now that I am the last one to post, I will have a blue indicator, but previous to this, you did not because it is by design only an indicator for the OP to have.
If so, that’d explain why I was confused as to why some topics had it and others didn’t. I expected it to just highlight whoever the last one was.
