I made the layout so that it tries to be as compact as possible,
so it will not break lines if there is enough room horizontally. Of
course, this might not suit everyone, but it suited me at the time.

Yes. In hindsight, maybe I should have added more hooks after all.
Perhaps I can still change it and remain backwards compatible.

If you add annotations to the nodes you want to handle, as a prepass,
you should be able to trigger the hooks and do the formatting your way.
