Problem: When using Special:WhatLinksHere, many of the results aren't in the body of the article, and are just from templates (especially navboxes) - this often makes finding results in the content of an article much more difficult than it needs to be.
Proposed solution: Special:WhatLinksHere already has (redirect) and (transclusion): add (template link), with a toggle to hide/show results that only link here from links in templates. Ideally, show the results nested in the same way that (redirect) links are - so if a template links to the article, show all articles beneath that.
