I will create an open-source application for management with Kivy and I want to have a menu to choose between the languages: Spanish, Galician and English and that the user can choose the one they want.
And then another file where the configuration is saved / loaded each time the application is started.
It occurs to me to create a settings.txt file or similar with the line
lang = 0 | 1 | 2
with the value 0 (English) by default unless it is changed.
