No no I meant you. No worries if you don’t have the technical skills for it yet. Regarding the translation of the OS you can check the Location part of the forum. You’ll see that you can request to be the coordinator for a given language and then participate to the translation of that language for the OS (from what I saw it’s purely graphical).
Regarding the predictive text input you can follow this thread
And to add the keyboard as default to the OS you can follow orangecat’s first message
