Should I hide the multi-language selection button/menu if my app has only one language currently?
Suppose my app may have multi language in the future, but currently has one language only. Should I hide the multi-language selection button/menu, in order to avoid a language menu with 1 item only?
Originally I want to show the multi language button with one language only (current language) in order to tell user that there may have other languages in the future. Is it reasonable?
