Thread:Extension talk:Narayam/Auto show option for Language/reply

That option is not available in Narayam. Narayam input method selection menu is shown if there is a input method available for user interface language or content language. From the menu, it is always possible to select any input method using the "More input methods section" and it shows the recently used input methods at the top of the menu. I don't know what use case are you trying to solve.
