It would be really neat if we could make multiple "profiles" for each account. It would allow easier sorting of shows when your family uses one account. For instance, if my Mom watches the same show as me, but I'm ahead in the series, then she has to remember what episode she was on and has to go to it, while separate profiles would allow me to have my spot saved, and she could have her spot saved as well. Or if someone else in my family likes Chinese or Japanese shows, and I'm only interested in Korean shows, then the interests could be split among different profiles so that I can easily get to my shows on the "continue watching" tab without having to sort through multiple other shows that I'm not interested in.
I would say that Netflix is a good example of multiple profiles, I would just say that it would probably be easier if you automatically logged onto the most recently used profile and you could change it from an option in the home screen.
