It would be neat if you could add a few stops on the line you are driving to simulate a service with an unusual formation (such as Vectron with Dostos, I am doing that right now) because I don't always know when the next station comes. This would be very neat, so I don't have to just set the final destination as my destination and then guess when the next station inbetween comes. or alternatively it would be cool if when adding a go-via point, it will get added to the schedule as "go via - as indicated"
I agree, have had the same thing and too add to this, potentially the ability for a load passengers (although I get that may be a bit much to ask though)
