Yes, thanks, I do see that now when I put on my microscopic glasses. I think it used to be that the comments were unrolled so you could glance through them, rather than having to click on 1000 comments to see what the responses are. (We often have hundreds of comments in a proof, and almost always someone answers each one, even if it's to say "ok" or "ignore this."
It's now cumbersome and impossible to scan -- similar to the changes they made to the Community emails -- more clicking, less visibility, worse user interface. I'm really upset at the backwards way this tool is going.
