It would be nice to have sub-titles displayed on the screen for the spoken dialogue in the missions. The man who narrates the first "Training" mission speaks pretty softly, iirc. Or, it's just because the air conditioner next to my room makes a lot of noise. So, to make it easier to know what's going on in certain environments (noisy ones) or where a person has to keep the volume down low for a sleeping spouse (or whatever reason) subtitles for the narration and spoken dialogue in missions would be a nice feature update.
Thanks for reading!
