+## 2026-10-23: Shift+Q/E build tabs, G pick key removed (Claude Code, with Codex)
+
+Notes: "add shift + q/e to move tabs" and "having the "g pick" there is confusing".
+
+- `src/ui/build-menu.js`: `selectBuildCat(c)` (shared with tab clicks) and `cycleBuildCat(d)`;
+  the menu hint now reads Q/E cycle · Shift+Q/E tab.
+- `src/ui/input.js`: Shift+Q/E switch tabs with the build tool; G is unbound.
+- Text: build card (`selection.js`), notebook controls (`notebook.js`), `actions.js` comment,
+  `docs/DESIGN.md`, `docs/PROJECT_MAP.md` (regenerated, `--check` passes).
+- `test/play.py`: checks for Shift+Q/E, wrapping, the remembered piece per tab, plain Q/E,
+  and that G no longer calls pick while middle mouse still does (109 checks).
+- Tests: all 11 headless suites and `play.py` pass; a `tools/shot.py` shot of the Moving tab
+  shows the new hint. `t_smooth.py` passes, but its "half-resolution smooth still draws" check
+  failed on several runs with the 'slow' pixel fallback while the machine was busy (load ~14).
+  The previous commit fails the same way under the same load, so this change didn't cause it.
+- Open: that check is timing-sensitive on a loaded machine; rerun it when the machine is idle.
