More answer feedback components
Thumbs Up and Down
Two small buttons under an answer. Pick one to rate it, pick it again to undo, and see a short thank you.
Thumbs Down with Reasons
When someone marks an answer as bad, a small panel asks why, with quick reason buttons and an optional comment.
Was This Helpful Bar
A short question at the end of an answer with Yes and No buttons. It turns into a thank you once someone answers.
Compare Two Answers
Two answers side by side so people can pick the better one, or say both are good or both are bad. Useful for testing models.
Report a Problem Dialog
A report button opens a dialog to flag an answer, with categories and details. It traps focus and closes with Escape.
Satisfaction Scale
Five faces from very unhappy to very happy. A quick way to ask how a chat went, drawn in SVG so it looks the same everywhere.
