There is a new feature coming to WhatsApp that could prove useful, but could also rub people the wrong way. The feature in question is called @all, and as the name suggests, it will allow users in a group chat to alert everyone at once, instead of needing to @ them individually. “Alert everyone in your group chat about important, time-sensitive messages. No more tagging people one by one or hoping your message gets noticed in a busy group chat. This should be handy for group admins, or those handling group chats where large numbers of members are needed to make decisions.
