Reactions in Practice
Emoji Reactions are a great way to communicate meaning to messages. In the example below, the 🆕 emoji is added when the request is create and waiting to be assigned, then 👀 is added once someone is looking at my request, and finally ✅ is added when the request is resolved.
This pattern allows you to quickly scan a channel to understand the status of each request.
Adding a reaction to a notification message is easy, just select the notification step from the Mission and then choose the emoji. All of your team's custom emoji will appear here as well. 🎉
Removing a reaction worked exactly the same way.
