- Focus the Kagi search field.
- Begin typing "bala…"
- Wikipedia page for "Balanitis" appears, including a small photograph of an inflamed penis, even with safe search enabled.
I wouldn't expect that to be the first hit, for one thing (surely something with "balance" or the game Balatro would be more common), but even if that's the article selected, Kagi shouldn't display that image, at least if safe search is enabled.
(However, I would be in favor of preventing all NSFW images from appearing in the search suggestions dropdown, even if safe search is turned off. Let me know if you'd like me to submit that as its own suggestion.)
