Idea: Use the scroll wheel to swipe between the choosen languages OR have a swipe language click-button on-screen.
Now: For example I want to translate ENG to GER, so I choose ENG, then GER, then I talk, R1 translates and…… if the other person has to answer (which mostly is the case) I have to go back into the languages menu, choose GER, then ENG, the other person speaks, R1 translates,……”one eternity later”….
