Note space not related to time stamp.
I'd love to use this as a formative assessment tool with my students. It would be great if there were a small space under the video/above the note taking area/below the not title... where I could post a quick note giving a brief introduction or information they should know. That way I could ask some questions... and they could tag where in the video they found the answers and what their understanding is...
You can actually achieve that by putting notes and distribute a copy of it via Google Drive to your students.
Please let us know if it works for you.
