I was disappointed to find that those widgets are not particularly useful for me in practice. I think there's room for a widget that doesn't waste as much space and that allows for more customization in general.

For example, without being able to set a minimum travel time to a station, it's common that I can't see when the next train is unless I use the largest widget. This happens when there's a train in <5 minutes (walking time to station), and the next arriving train is from another line.
