Why don't we have this option??
At the end of any conversation dialog, I want to simply hit the escape (esc) key to exit it -- especially if there is only one option left at the end, like "Goodbye" or "Close Connection". Currently, I must hit the corresponding number key (usually 1). This drives me nuts, as Esc works to exit from just about anything else, including exploring planets.
What's worse, in the dialogs where your planet exploration crew narrator guy (I don't think we're ever shown his name) is speaking, I don't see any number keys shown on the screen; so the only ways to exit those dialogs are to click on the X icon or press the 1 key. Seems small, but this game has a TON of (absolutely amazing) dialog, so the sheer number of times I have to deal with the "1 instead of Esc" issue makes it super annoying.
It seems like this should be a relatively trivial fix, and would make my gameplay experience significantly better.
