My first try to create a gui for fahrplan2 engine. Created with qt widgets because I have no clue about qml.
So I will attach a binary development preview from fahrplan2 engine (ver 2.0.26).

No translation, no calendar, no gps function. At the moment it creates a config in /home/user/.config/smurfy/fahrplan2.conf so it will not conflict with fahrplan and you can have both applications running.

When it is ready it will replace fahrplan package. But don't know when it reaches this state.
