Currently Special:WhatLinksHere shows three link types at once: page links, redirects and template transclusions. Sometimes it's useful to browse them at once, but sometimes it's not. For Wikimedia, there is a workaround "WhatRedirectsHere" Toolserver tool [1], but if you want other options than just redirects, you will have to extract them by hand.

My proposal is to add "selectors" to that special page, same appearance as in Special:RecentChanges:

[Hide/Show] page links | [Hide/Show] redirects | [Hide/Show] transclusions

For compatibility, all of them should be turned on by default.
