Just noticed something neat in macOS Sonoma: as you know, #Safari now shows favicons in your bookmarks bar. But if you rename a bookmark and add an emoji, that emoji acts as a custom favicon ✨

@nileane Favicons was the main reason I couldn't use Safari as a heavy user. So glad they're finally here.

iirc Safari had Favicons in the favorites bar at one time, but that feature got removed some time ago.

I remember people complaining about that "some time ago" indeed, but I thought I eventually heard relief from that group when they were reimplemented. The time of that reimplementation, I'd have guessed, was at least five years back.
To be clear, "the favourites bar" meaning the optionally-visible strip beneath the address bar? I wasn't thinking of that just now, but I've just checked the current version (Ventura) and they're there.
