I would like a search bar for the questions and answers for each video, so we can search for a particular Q or A, such as seeing if someone else has already posted a question on what we were wondering about. One of my posts got flagged because it was a duplicate question, but I didn't know it because there are lots of posts on a video, and I couldn't see if someone else had already asked it. I think that this feature would serve me and others in the future.
