Choices, reactions and branches
Choices
When a decision has a few clear options, your accomplice asks with a small choice wizard in the conversation instead of a wall of text: one question at a time, its recommendation marked, and Something else… to type your own answer. Use the arrow keys and Enter, or tap. Your picks go back as your next message.
A question you talk past (you write something else) disappears: it never nags.
Reactions
Press React under any message and pick an emoji. Your accomplice sees your reactions on its next turn, which is how a 👍 on a suggestion or a 😂 on a joke teaches it what you like. A reaction never starts a turn by itself. It reacts to your messages too, when a reply would add nothing.
Branches
Sometimes one message deserves its own discussion. Press Branch under it: a side conversation about that message opens in the canvas, and you talk it through with your accomplice there, away from the main thread. The message shows a chip with the number of replies. When you are done, merge the branch: the side conversation comes back into the main one as a note, so your accomplice has what you found.
