leech only downloads the main story threadmarks but sometimes you also want the apocrypha, sidestory, informational, ... threadmarks to read omakes or becouse they sometimes contain valuable information. Not sure what's the best place to include them as it depends on story what makes sense most. Sometimes you want them in order with the normal threadmarks (by date) other time it would make more sense to stick them at the end.
