I have some suggestions for new key bindings for the keyboard, to make gameplay more smooth. 1. Key bindings to open and close passenger doors. I suggest to use Numpad 4 and 6 for this purpose. They can be toggle keys.People not having a numpad, can still reassign the keys to other keys or keep using the Tab. (This is already known, but for completeness worth mentioning) 2. Game save function. Can we have the F2 key for save game? I would prefer no confirmation to a game save. It would be awesome to have a save game by route, instead of global for the game. If that is not possible, the resume saved game should be available at the start screen, before choosing a route as well. This feels more natural.
