Like the title says it's easier and faster to have a button to swap the languages instead of changing it maunally. Like this if i do english to dutch but then i want dutch to english. I need to change english in a other language like france then i can change dutch in english and then i can change france into dutch. This is a very long progress if you want to change the languages in text translations. first picture is the button what i'm asking for and the second picture is to show that the other language is not avaialable.(english is engels and dutch is nederlands.)
