I teach drafting and design to high school students and we use SketchUp for Schools extensively in my class. For some of our projects I do not want students using the 3D Warehouse (either because some have a tendency to try to represent others work as their own, or they limit their creativity to what components they can find in the warehouse). It would be awesome to either have the ability to turn off access to the 3D Warehouse, or create templates that do not allow importing of components.
