Hi,
I have released the internationalized version of this plug-in (ver. 0.13). In this version, I provide following language translation files.
Català
Deutsch
Español
Français
Italiano
Japanese
Korean
Magyar
Nederlands
Polski
Even if your language is not included this list, you can easily make your language locale file, because I adopt ART / RawTherapee style simple text file as language locale file instead of GIMP standard mo file. Locale files are in “locale” directory under this plug-in’s directory, and you translate default.txt to your language and save it as [Locale code].txt. For example, you would like to add Vietnamese locale file, save the file as vi.txt.
[Example of Locale File (ko.txt)]
You may be able to find the list of language locale code in [edit] > [preferences] > [Interface] > [Language].
