Due to GDPR and other complicated and dangerous EU laws, from now on (May 24th, 2018), this utility will no longer offer data storage releated features such as analytics (for improving the service), saving of the configuration to a cookie for easier editing, preview of the configuration file and dismissing of the language info. Files uploaded to this site always were and still are only stored temporarily and will be deleted after the generation of the configuration file. The privacy statement of my webhoster can be found here.
Currently, the default configuration is loaded.
Don't remind me again! (Sorry, no more cookies, so no way to make this happen...)
