Create .po file for volunteer to translate this plugin
same as title , make your plugin multilingual !!
you can gettext of python create the .pot file and use poedit (or other po file edit software )to convert it to .po file ,than volunteer can translate it to other language
you can find more information by searching "python i18n"
and you can also create team on Transifex and (or crowdin)share link to others people to help you for translation
(sorry for my english haha)
It's not enough to just create a po file and have some translations. Those translations need to work out of the box and detect kicad's and/or system language settings. This is low on my list of priorities which is why there is no progress so far.
Unless you want to contribute working code please refrain from meaningless comments.
