Yeah, I mean the UI text. you can find the .mo files in the project folder:
https://github.com/xxyzz/WordDumb/tr...r/translations
The plugin code is in the "WordDumb.zip" file. But for testing and debugging, you'll need to clone the git project. If you are familiar with git, you could send a pull request at GitHub. Otherwise, you could also upload the new translation file and I'll create a git commit for you.
