Player multitasking while running dialogue

[NobodyDrivesACar]

While in the middle of a conversation, the player character can't do anything besides reply with the given dialogue options. I'd like to be able to make it so that the player can, what say, whip out his cell phone and reply to a text while also holding a conversation in person. So you'd have the dialogue options on the screen, but you'd also be able to do something else simultaneously with the keyboard. Although I think you have to finish a dialogue before doing something else because it's a blocking function? And I don't just want a dialogue option such as "(reply to text/do whatever)". The button for performing an action in-conversation should be the same as the button for performing the same action outside of a conversation, for convenience. How should I go about doing this?

There's an option in General settings about Dialogs not blocking game loops. Try that.
