WHATSAPP WORKING ON CUSTOMIZABLE EMOJI REACTION SETS ON IOS

Summary from the TLDR Design newsletter

WhatsApp is testing a feature that would let users customize the six default emoji reactions shown when reacting to messages, replacing them with emojis of their choice and restoring the defaults at any time. The feature is not yet available to beta testers but appears to be in development for both iOS and Android, with a possible tie-in to WhatsApp Plus.
