Quip / WorkDocs means you start getting comments, highlights and other things from people -- which are then visible to everyone else at the meeting.
If there was a way for you to personally highlight your concerns during the read-through and then the presenter could display them all at once that would be great.
By not having that ability, it tends to mean the person with the "most authority" has their comment taken seriously and addressed straight away -- just like having the "loudest voice" in a meeting works against allowing everyone to contribute.
