Having many modules makes the startup module in the head unnecessarily longer. Things should only be in their own module if they're going to be loaded on demand on their own or are a shared dependency of separate modules that are. This change brings down the amount of modules declared by Media Viewer from 53 to 8. The ones that remain are mostly things loaded on demand.
