A web search's results and a reply's sources show their first seven, and the rest fold behind a button that shows them in place and becomes "Show less": "Show 3 more" under the results, and a "+3 more" badge at the end of the sources, whose count still says how many there are in all. A list that would hide only one shows it instead, opening one moves focus to the first link it showed, and both fold through useFold in parts/fold.ts. A thought now reads as a tool step does: a row with its chevron, "Thought for 12s" or "Thinking", and a muted glimpse of its first line with its Markdown left out, which opens onto the whole thought, in place of three lines fading out under a Show more. The tool views and web UI specs describe both, and the tests cover the folds and the thought's row.
