Sorry for the delay, I was out on vacations and I just returned.
I haven't use DoozyUI myself, so I don't know exactly how it is setup.
From my understanding (based on a quick glance of its videos), it uses the regular Unity UI, so, it should work just fine with I2 Localization.
If there is any part that its purely dynamic, you can always call LocalizationManager.GetTranslation(termName) to get the translation from the source and assign it to the label.
If DoozyUI uses a custom component for rendering the texts, you can easily add a new LocalizeTarget to support that component, its really easy. If thats the case, please let me know and I can assist you on setting that up.
Hope that helps,
Are you Give I2L 5 stars!
