Reactions, pins and stars
React with emoji, pin important messages for everyone, and star messages for yourself.
Reactions
Point at a message and click the smiley to add an emoji. Click a reaction under a message to add yours, or click again to take it off. Point at a reaction to see who added it. Viewers can react too.
Pins
Choose Pin on a message to keep it at hand for everyone in the conversation: a snag list, opening hours, a rota. Click the pin at the top of the conversation to see them all. Anyone who can post can pin and unpin.
Stars
Choose Star to save a message for yourself. Only you see your stars. Find them under Starred at the top.
