Sub-Wheel for Series in Big Box

[megashub]

I would like Big Box to support the ability for scroll wheel theme views to leverage a second, nested scroll wheel in order to scroll through games in a series. This would need games in a series to be stacked and displayed visually as a stack in menus. When a user selects a series stack, the user is presented with sub-navigation which allows for scrolling forward or backward in the series, running in the opposite direction of the main scroller. So if, for example, the selected view is a vertical wheel, then the series would scroll horizontally, and visa versa for horizontal wheel views.

This feature would allow for a less cluttered game list, while still providing easy access to all games in a series.

Nice-to-have: Allow the user to select which game in a series to feature on the top of a series stack. Example: The Street Fighter series. User selects Street Fighter II Turbo to be the featured title in the series, and sub-scrolling is possible backward and forward in the series when selected.
