I should also add that you can also edit everything directly in the editor:

• Add a script and input/output files via the "Tools" menu
• Delete files with the link at the top right of each file
• Rename files simply by editing their name
• The "Copy URL" function will get the URL of the current state of the editor into the clipboard
• Update: Also, set options like the brand new "autorun" (applies to the copied link) and "merge STDOUT + STDERR" via the "Tools" menu
