Currently, you can place tags on handouts (assuming that's what you mean by "notes" =D). Macros you can drag around to reorder. For ordering handouts, you are restricted to your choice of name. You can preface the name with something to affect the order, but that's about it. Be aware that the search by tags or name is a union (so if you search for "cat" and "dog" you'll get anything with either "cat" or "dog", not only things with both "cat" and "dog").
