Notation looks good. I still found this inconsistent behaviour:
- select both notes and notation events
- drag the event in a continuous view up/down from track to track -> notes are moved as well
- drag the event in a single item view up/down -> notes are note moved
- drag notes left/right in both views -> events are moved as well
- drag events left/right -> notes are not moved.
Expected: everything selected is being moved.
