File config.php: There are a few places in the code (such as the admin panel) where boolean configurations need to be fixed as of 10/08/2011.
Member get_custom_nav (&$a, $navname): not fully implemented yet
Member RedChannelList (&$auth): Is there any reason why this is not inside RedDirectory class? function name looks like a class name, should we rename it?
Member RedCollectionData ($file, &$auth): Is there any reason why this is not inside RedDirectory class? Seems only to be used there and we could simplify it a bit there. function name looks like a class name, should we rename it?
File reddav.php: split up the classes into own files.
Member RedMatrix::__construct (&$auth): disable enablePost by default and only activate if permissions grant edit rights.
Member RedMatrix::set_writeable (): Maybe this whole way of doing this can be solved with some $server->subscribeEvent().
Member RedMatrix::getDir (): add description of what this function does.
Member RedMatrix::setName ($name): handle duplicate directory name
