I've already said this multiple times in this thread but just a reminder : it doesn't work like that for sub-folders. I've tried to list my applications by alphabetical order, didn't work. Folder's use the .desktop of the app and thus are arranged automatically by that order, not by the alias (e.g. osso-calculator.desktop would be Laskin (Calculator). So far we don't know how to make the listing alphabetical, unless the programmer himself would find out how to do it.
