This would be extremely helpful when planning/scheduling to watch different sections!

Yes, this would be very helpful when planning study time since we need to balance our study time with other subjects/courses.

3 years later, this suggestion has not yet being pushed for implementation. Please anyone, it is a very much needed feature for better planning.

Best regards

Yes.  Please!  I realize that many users work independently through "courses," but as someone guiding students through the material it would be extremely helpful if there were estimated time per unit (length of videos at least) for planning purposes.
