Peek at a trace without leaving the list

Clicking a row on the Traces list now opens the trace in a peek sheet beside the list instead of navigating away. Triage usually means walking down a sorted list, and a full page load per row used to cost you the sort, the scroll position and the filters each time.

The sheet shows what the trace page shows: the waterfall, timeline and flow views, and the span detail pane.

• ↑ ↓ or J K step to the neighboring trace.
• Enter or Open trace opens the full page, keeping the span you selected.
• Esc closes the sheet.
• Cmd-click, Ctrl-click or middle-click a row, or click its trace ID, to open the full page directly.

The open trace is part of the URL, so reloading or sharing the link reopens the same view. On narrow screens, a click still opens the full page.
