Add selection of the Colors (display quality) to enable slow speed networks
Allow the display quality to be lowered (the in-store app goes down from 32 bit to 8 bit) to speed up on slow connections.

This is a wonderful suggestion, especially when you consider the mobile nature of this application, and the variance between cellular connectivity, performance, and experience.
Allow customization of display quality and speed from the settings/preferences panel - eg. compression type/compression rate etc (not only resolution and color depth) so that the user can optimize the viewing experience depending on his current connection speed
