Hi,
You can edit the success message via the free Labels Edit add-on.

There are also hooks in place to filter all the success messages, just let me know which one you want to filter and I’ll send you a code snippet.

The reason we used hooks or a dedicated add-on for this is because we didn’t want to overload the interface and keep it light for people who don’t need this specific functionality.

Since we’re constantly improving the plugin based on user feedback, I would also love to hear the other options you feel are missing from it.

Thanks and regards,
