Allow adding categories as well as titles under a category. For instance, creating a “Marvel” category it would be nice to add “Iron Man” based on metadata new movies will already automatically be added to the “Iron Man” category which in turn should automatically add them to my “Marvel” category. Also, it would make creating something like a “Marvel” category much faster even if it didn’t automatically update.
Similarly it would be nice to have auto-tagging to create dynamic categories based on a filter such as ratings, actor, tags, etc. In fact, under the hood this feature could be used to implement the above. From a UI point of view it really is odd that you now edit tags to create categories but select categories rather than tags to display them.
