In this version, all of the strings in the UI have been externalized out of the source-code and in to the java properties file. This properties file can be found in the sce folder of the lib\SceneryConfigEditor-$version.jar archive. In order to provide translations for the interface all one needs to do is to add a copy of that file into that folder as scenery_config_editor_LANGUAGECODE[_REGIONCODE].properties. One need not provide translations for all the keys in the file, see
