Comments

Threads anchor to nodes, not to a document somewhere else. Anyone who can see the canvas can comment and resolve; deleting a comment is for its author or the canvas owner.

• A gold count dot on a node's corner means unread comments. Click it for the thread right there; Open details jumps to the sidebar.
• Collapsed containers roll up their children's unread dots, so a buried conversation still surfaces. Clicking a rolled-up dot opens the newest unread thread inside.
• Reading a thread clears its dot — for you; each person has their own unread state.
