A nice little thing from Google: 9 emoji reactions with unobtrusive animation appeared in Google Meet. They are available for all calls without encryption enabled.
Google first announced this feature last year, but it's only now reaching users. There is now an icon with a smiley face on the bottom control panel in Google Meat. If you click on it, you will be presented with a choice of nine reactions (with support for different skin tones).
When users respond with emojis, you see a small icon in the top left corner of their web tile. And if several meeting participants use the same reaction, a Match occurs and a full-screen animation is played.
Reactions will be enabled by default, but the meeting organizer can disable it for a specific call. The feature is rolling out gradually.
