remove non-functional "Allow Diagonal" property for Note-Anchored Line
- Enter two notes with different vertical positions
- Ctrl/Cmd+click select them
- Add → Lines → Note Anchored Line
- In the inspector uncheck "Allow Diagonal"
Expected result: the line becomes horizontal, following the height of the first anchor point (as per other lines)
Actual result: no change is seen, the line remains diagonal
Use case: Music analysis where you want a both-ended hooked line above the staff from one notehead to the other. Using a staff line is not an option in this scenario as the endpoint anchors to the end of the duration instead of the notehead itself.
