Scripts kept in the .fry (the Script panel lists the file's scripts: new, examples, open, duplicate, remove, rename); your own materials (Save its look as a material, kept for every file; fry.material in scripts); plug-ins: scripts in the plug-ins folder that stay loaded and add menu commands with settings (fry.command, fry.plugin), a Plug-ins window, three that come with it (stairs, scatter, more materials); a new About window; tests
