Subway/Metro/Bus app improvement suggestion

I quite enjoy the public transit apps from an aesthetic perspective, but wanted to suggest adding some functionality improvements.

It would be great if you could set the app to show trains going one direction only from a given station, and list the three coming trains with their ETAs on a single display.

I presume most folks only head one direction from their station most of the time, and this would enable people to actually plan a departure time from their home.
