YouTube New Video Interface
YouTube updated their video interface today. While it looks nice the interaction design is poorly thought through.
The buttons for share, playlist, and flag buttons each act as a tab and open screen area to provide more options. The favorite button marks the item as a favorite. The buttons should have the same interaction, which seems to lead to open for more options. Marking the item as a favorite does not have options and most likely should be a check box or other interaction pattern, just like the "Rate" area is its own design pattern that maps to its interaction type.
This is really poor design thinking.
