I have just modified Conditional Decorator to have the option to return Success or Failure (default is of course Failure like before). I have attached the modified file for you here as well.
A new version will appear online as soon as I complete working on a new planned feature to warrant a new version, unless some important bug is found in which case an immediate hotfix will take place (thankfully none right now) :).
Also yes, I do send local versions to users with invoice over email no problem. Let me know if you want to 🙂 (support_AT_paradoxnotion.com).
