Add the option of typing messages on one device back and forth to each other. Like texting, with dialogue boxes of different color to differ
I would like to be able to pass one offline device, phone or tablet, back and forth and hold a translated text conversation. Like texting, we would each have different colored dialogue boxes to differentiate the "speaker" and the conversation would scroll up. Each of us could have a colored button at the bottom that matches the color of our respective dialogue box, that we press once to select the current speaker and initiate our next dialogue balloon. A vertical split screen would keep both sides translated continuously. Basically two columns of running text balloons in two languages. We could sit somewhere and have a quiet, unobtrusive conversation. She could read what I was writing as I wrote it, on her side.
