It would be great to have the plugin localized in multiple languages.
This issue is definitely contrib-welcome... if you're a user of this plugin whose native language is not English, please help us by providing a translation!
Currently all the strings that appear in the plugin are configured in HbBundle.properties.
The easiest way to contribute a translation would be to open an issue for the language you are providing, and paste a translated version of HbBundle.properties into that issue. (Of course, feel free to send a pull if you know how to include the localization, but please don't feel pressure to do it end-to-end. Simply providing the translation would be a massive help)
Once that's provided, I will make sure the language is included in the next release.
