Yes I understandood your point/proposal and it could be the easy/mainstream logic for most people...
but that would mean to develop a new piece of settings and logic (feasible of course) when up to now, I was trying to mainly tweak existing main code.

And as you suspect, when it comes to other scenarios to consider, there are plenty  . For example I also often watch my movies in English with English Subs either in order to practice and improve my English, or when I do not have french subs at all.

This needs some thinking...
