The software is licensed under GPL3 (as you see in the About dialog). You find the source in Maemo Garage (project MovieSchedule with git repository).

You can use the QtTranslator to translate all strings. A german translation is already present. You may copy your translation to /opt/maemo/usr/share/movie-schedule/translations/ on your N900 to test it. If you send me the translation I will add it to the next release (How can I release new translations without going through this testing process again and again?)

I used the rotation shortcut, thanks for the tip. If I add support for rotation I need to fix the calculation of the vertical texts and the layout of the About dialog.
