Watched for the first time just now. I love the PoV videos! It's really helpful to see just what the hands are doing, and no cuts.
The biggest gaps in written IMHO tend to be (a) things people do but don't realize they do, (b) things people do but assume everyone else already knows, (c) things people do more efficiently but don't think to mention (obvious example: use a cook time break to clean prep-ware).
