Threads, reactions, mentions, presence, drafts, scheduled sends, saved messages.
Reply in thread
Spin a follow-up off any message without derailing the main channel.
Reactions and the emoji picker
Acknowledge a message without writing a reply — and find the right emoji fast.
Mentions and the mentions feed
Get someone's attention with @ — and see every time someone tagged you in one place.
Presence, typing indicators and status
See who's online, who's typing, and let your colleagues know if you're in a meeting or off sick.
Drafts and scheduled sends
Per-channel drafts (local to your device) and scheduled messages you can cancel later.
Saved messages and pins
Bookmark messages for yourself (private), or pin them so everyone in the channel sees them.
