+# 036 — Open a section in its own tab
+
+## Summary
+
+`App.tsx` has no routing at all — `NavMenu`, `FilterBar`, `LogTimeline` +
+`LogPreview`, Params ([034](034-params-declaration-ui.md)), `Metrics`, and
+`Dashboards` all render together in one fixed layout
+(`webapp/src/App.tsx:94-108`). Add a small icon next to each section's
+collapse toggle ([035](035-collapsible-sections.md)) that opens *just that
+section* in a new browser tab — no `NavMenu`, no other sections — for
+pop-out/multi-monitor use.
+
+## Scope
+
+- A "pop out" icon button in each of the four section headers (Log viewer,
+  Params, Metrics, Dashboards), alongside the collapse toggle and "?" help
+  icon.
+- Clicking it opens a new tab (`window.open`, not same-tab navigation) at a
+  URL identifying that section, e.g. `?section=metrics`.
+- Minimal client-side routing in `App.tsx`/`main.tsx`: when a `section`
+  query param is present, render only that one section full-page — no
+  `NavMenu`, no `FilterBar` unless the Log viewer section needs it, no
+  sibling sections.
+- The standalone view keeps the section's own functionality intact (e.g. the
+  popped-out Metrics tab can still declare metrics; popped-out Dashboards
+  can still edit/autosave panels) — it's a layout change, not a read-only
+  view.
+- The popped-out tab reflects the current `range` state (time range) at the
+  moment it's opened, passed via query params, since it has no `LogTimeline`
+  of its own to select one (unless the Log viewer section itself is what's
+  popped out).
+
+## Acceptance criteria
+
+- Clicking a section's pop-out icon opens a new tab showing only that
+  section, with no nav bar and no other sections.
+- The popped-out section is fully functional (not a static snapshot).
+- Closing the popped-out tab has no effect on the original tab's state.
+
+## Depends on
+
+- [035 — Collapsible primary UI sections](035-collapsible-sections.md)
