I tried to translate it (italian), but it is not complete (I have to look at your app and see what are "shifts").
But I have an idea, I do not know in to which section put it.
We could ask to create a special section in the site in which, as in your case, a person shall publish its translations made with Google Translate and asks friends in B4A to correct them.
Ask to translate everything, even if in only one language, it seems to me exaggerated (i need this too, but i do not dare to ask so much)
