Leaked WhatsApp Feature Allows Users to Create Customized Stickers Using Their Own Image
(www.techtimes.com)
This is a most excellent place for technology news and articles.
I use similar feature on discord quite extensively (custom emote/sticker) and i don't feel they are just a novelty. Allows us to have inside joke / custom reaction to specific event and I really miss it when trying out open source alternatives.
