I agree it would be nice to have a way to print out all the comments in an inline review and I also agree it would be nice to have higher limits on the content per box in an inline review, but call me crazy, I don't understand it being too difficullt, tedious, time consuming, whatever to look for the individual comments either the original by the reviewer or the response to the review. Seriously, you're not talking humongous amounts of time here, maybe a few minutes max.
When I get an inline review, I look at each box and generally will leave a comment in most. After giving an inline review, I go back to check to see what if any comments are left by the author in each and every one of those boxes and may leave additional comments. Others can comment also, though I'm not sure most are aware of that function since I haven't seen it utilized to date.
To the point, if receiving comments on our work is not important enough to spend a few minutes to check them out and/or respond, then we're not really that hyped on getting feedback imho. That's the way I see it. Take care. Vern
