Hovercards displays a pop-up for some links in Flow:
- "Thank" links at Enwiki, e.g. https://en.wikipedia.org/wiki/Wikipedia_talk:Flow/Developer_test_page
- "Block" links at MediaWiki, e.g. https://www.mediawiki.org/wiki/Talk:Sandbox
- “Permalink” in topic menu drop-down at Enwiki, (with introduction of “topic” in English interface)
(But this old issue seems to be fixed
- topic name in watchlist if it match an article. )
