Actually, I feel not qualified to judge here.

Filling 'side-support-elements with NoteHeads and Stems made things even worse.

Currently I see only two alternatives:
- Abandon it. Which would be a pity. I first worked on #3176 3 years

- Polish the patch and add a warning in NR. Basically: only works in Score.

Opinions?
