I got two feature requests for TSW3: I think it'd be great to being able to leave a scenario immediately without waiting for the game to do it automatically for ourselves when we're AFK. It can be useful when we want to enjoy the passenger mode view without delaying trains. Adding Time Skip for the passenger mode is a good idea in my opinion. It can be useful when you're waiting for a train coming in 40 minutes without quiting or selecting a service starting later in the timetable.
We could certainly do with a 2x or 4x fast forward when not actively driving, though would this cause issues with the complex calculations of all the other traffic.
