Not only textures and templates, however, but also material and object grouping. Some 3D programs deal with only material groups and others deal with only object groups. Some deal with both, though. You can take an object which has only one material group, and make each object in it a separate material. You can split objects apart into two different objects. You can make objects out of material assignments. And uou can do all that with just the regular, free UV Mapper. All kinds of good stuff, but you are right. If you aren't modeling or making your own textures, aren't planning on making CR2 files, UV Mapper wouldn't be something you'd need.
