LPLs from displacements

If you move a period to a position in the timetable or the scheduling dialogue which is already occupied and where a swap is not possible, you can displace the existing lesson from the desired position. A prompt is displayed asking, "Move the conflicting lesson to the 'Lesson Pool'?". If you confirm with <OK>, the respective period is displayed next to the timetable and in the 'Lesson Pool' window.
