The ScriptedImporter class is a welcome change. However, I'd like to have assets with a particular extension to have an associated icon - instead of the default Unity3D one. Is that possible? It would be nice to have that wrapped into the ScriptedImporter attribute similar to this ... Code (CSharp): // Custom importer for *.foo files [ScriptedImporter(1, "foo", "Assets/Path/To/Foo/Icon.png")] public class FooImporter : ScriptedImporter {     // Importer details ... }
