All Mint tools are localized. “If” given the proper translations, they can virtually run in any language. Otherwise they just default to English.
We have a week or two before the stable release and whether these tools will support your language or show up in English instead depends entirely on you

When replying and posting a new translation:
- Make sure to indicate which language you’re translating for
- If possible, take the time to test your translations
Many thanks in advance to all the translators. We’re hoping to use an automated tool to coordinate the translations in the future, but if we all get to it this week on the forums, we’ll quickly get to a stable release with full support for most languages.
