Most of our projects span multiple months from start to finish. Within that time, we can sometimes end up with several dozen comments in our communication section. This would be much more organized and easier to navigate if when replying to a comment, it created a "conversation". That conversation would have its own string of replies that are viewed by clicking on the conversation. Clicking on it again would collapse it back to only the original comment being visible in the communication section with a little indicator that shows it has replies within it.
