Someone asks a question in the Chat menu for everyone and I have a similar question. So, I want to reply to this message with "I have a similar question" or "Good question" or give an emoticon for this question. I cannot do it because Zoom only gives Copy in the Chat menu.
Note that this feature is a part of the Q&A window available in Webinars. Perhaps being able to add a Q&A window into Zoom Meetings would meet this need... leave Chat for basic banter back and forth, and have (an optional) Q&A window for people who have questions for an instructor or presenter in a Meeting, as an example.
