When one links (wikilinks) to another page ([[Some page]]) and that page is renamed, all links pointing to it are updated to match the new title. Great.
When one does the same to a section within the current file (e.g. [[# Section]]), links do not get updated. In fact, they don’t even show as broken; they simply stop working.
Proposed solution
Extend the link update feature to also apply to section links.
Another idea for this would be to make a way to refactor a heading into an new note and in opposite direction. Like when we refactor the content of a heading it automatically update all the links to that heading to a new note. That would be make the natural evolution and expansion of a note so much smoother.
Also related: updating backlinks to a linked block when it is cut from one note and pasted into a different note. Not sure why this one went to the feature archive.
