1. No, we don't allow upload all types of files to prevent cute editor used as a hacker tool because the file upload function is so powerful.
We have an internal files type array which contains all the files allowed to upload. Even you add <item>.myfiletype</item> into the security policy file, this file type will be restricted if it's not in that array.
2. In the next version, we will add an option to turn this feature off so you can upload any file type you like.
