Signal just released a "poll" feature with great fanfare, while all #deltachat apps already integrated a full suite of chat-shared apps, checklists, polls, shopping lists, calendar, editor + tons of games.
Better, anyone can create new apps, eg as github/codeberg forks from existing apps, and post it to their chats for instant deployment. No need to ask for permission, register an account, and no hosting or DNS: actually "server-less" and fully end-to-end encrypted :)
