It would be great to add support in a future version of Linkchecker to scan menu blocks (or scan the underlying menus) to find broken links. We have a use case where we are using the Linkchecker data tables to examine internal links and find orphaned pages, and it would be great to take into account menu links. It's very easy for menu links to point to nowhere or become broken links over time as a site ages.
Has this ever been discussed? Anyone else interested? Does anyone have a patch or some code to start on?
