I like the everything in one folder idea. It makes sense to have common files like the basic geometry files in their own directories, but a new geometry and texture folders for every prop and custom figure is a pain. I also wish folks would adopt a common naming convention. One other thing, with long file names available, I really don't see a compelling reason for short cryptic names that tell you virtually nothing about the file contents. I end up trying to rename things as I download them.
