In Manage Themes Collapse Type Models by Default

In Manage Themes, when you expand a theme, all types and type models are shown. In 99% of cases, I only want to see the types and not the type models, so in most cases the expanded type models are just noise.

When a theme is expanded, I would like the type models to be collapsed by default. This will provide a better overview of the list of types.
