Had a attendee ask this question again this weekend... any chance of adding reactions in the chat?
I use Slack and one feature that they have that might be nice on the chat is the ability to add a sort of quiet response to a specific comment.
Mathew commented that "Amy is so talented"
On Slack I could add a response (smiley face, thumbs up sad face, 100+, etc) to indicate that I agree, but no interrupt the rest of the chat stream.
Might be worth a thought.
