Bookmarking videos

I don’t often have time to work through a complete video. I may have to stop halfway through, for example, and pick it up again on a different day. It is then frustrating to have to find where I was in the video – of course it is often useful to review previous bits, but still … as I said, I don’t have much time. It would be really useful if I could bookmark videos so that I could go back to the exact point where I left off. Bookmarking would also be good for highlighting key points.br

Would this be possible?
