adding a new language, any way to mass apply?

It looks like there's some smart handling of the font issue, I'm getting Cyrillic without doing any extra settings

Haha, yes, the process was made even simpler.

You just need to create a term in the LanguageSource for localizing the Font (e.g. Name: "Arial", and select the font for each language).
Then, each label automatically tries to find the term that is named like the font name and apply the translated font.

That way, you don't have to select the secondary term for each label, just create the term for the font you use in the editor and the plugin handles the rest

By auto-fill do you mean to add a button that translate to all languages that don't have a translation yet?
I mean, a button to avoid having to click Translate for each of the languages?

That has been on my todo list for a while. Even more than that, I want to add a similar button to the Language Source so that it auto-translate to all languages that you haven't add a translation yet. A similar thing for when you add a new language. So that by default you get the translation of all terms.

I have been holding that as I wanted to also add a flag to the translation to know when they have been added by a Human Translator or when they have been Auto-translated by Google Translator. Now for I2L version 3 I changed the structure where the translations are stored and added this flag, so its the perfect time to add that feature!

Thanks,
