We have a host of video training series that we would like two common features added. First is a progress %. This way the user will know how far along in the training they are if they step away from it. It reinforces progress and reinforces accomplishment when complete. Second is to have a training series where the 2nd model remains locked until the first is complete ... and the third is locked until the second is complete and so on. This helps people to focus on completion as they are prohibited from skipping forward as well as it creates focus and scarcity and they are missing out on future models until they complete.
