I enjoy the timetabled activities, but I have a small suggestion to improve the way they're presented. At present the menu sorts them by time, so typically you get a series of short "move a train from the depot to the station", followed by a lot of "drive a train from A to B", then some "move a train from the station to the depot". It would be nice if you could also group these into orders that reflect the duties a real driver would perform in a working day, so you could do a series of activities (grouped, say, under "shift 1", "shift 2" etc.) that save you from having to scour the list for the next likely service after the one you've just done.
What we need is some sort of advanced filtering system, that way we can sort the timetable services in the menu out as we please.
Also why not present in a proper timetable format. the old Japanese Densha de Go Professional did that, allowing you to click on the header at the top of the column to select the train.
