robinwak Good to hear some changes are in the works. One major pain point does not seem to be addressed is the hard requirement to 'post' comments. For those of us who do most of their commenting and editing offline, followed by a one-time share to the coauthor, this is a cumbersome step that adds a point of friction tens of times per editing session. Please reconsider the requirement of posting/sending comments, and make sure there is a mode / optional setting that allows for seamless posting of comments (i.e. no accidental scrolling way back up to some 'non-posted' comment).
I'm not saying the ability to post and notify should be removed completely. In fact, I think this kind of distinction between posted and non-posted comments would improve productivity. When I'm editing a document and I see a major issue that I want my collaborator to get started on, yes, it's great to be able to immediately 'send' a comment, alerting them to the issue. But for non-urgent statements I don't need notifications sent out, and I don't want to spend extra mouse click or key presses to 'send' / 'post'. In that case there is no benefit to 'posting', and the author still has to do this extra step for every single comment. That's counterproductive.
tl;dr Please reconsider the requirement of 'posting' all comments and carefully consider its impact on less interactive workflows.
