I join the chorus. I truly detest the new comment structure. So far it has only slowed down my work and I fail to see any advantage. I don't know why I just started noticing this recently as I use Windows365 so would have thought to see it months ago, but only in the last month did it rear its ugly head. I started trying to figure out where the comment bubble was and why my cursor kept jumping around when I hit the new comment button. Then I discovered all of my recent comments were in one completely unrelated place miles up the document, because I didn't hit a command enter button. I see no need to have this "conversation" approach to commenting on a paper. Most of my collaborators don't wish to have a conversation on every item - they are busy people also and they want to see a document with edits and comments all there, easy to find in whatever version of word they might be using. Not everybody updates their software frequently, they may have compatibility issues. At first I thought this unfortunate "upgrade" was due to downloading a word document from a collaborative Google Doc version, but now I'm finding it on other papers people are giving me to edit. I think Modern Comment would be something that could at very least be an item to be chosen as a preference, and not simply presented as fait accompli.
