Let us mark multiple comments and quote them in 1 comment, instead of quoting and posting a comment for each of them.
that only makes sense. if you want to reply to 5 people who already made 5-7 comments, you don't want to make 7 more comments to reply to each of them. 1 comment to reply to them all keeps the threads clean and organized.
this design exists on other forums and it's already proved to be useful in the field.
