 - **Axis cap** - `binning::MAX_BINS_PER_AXIS` (64) keeps any future MCP payload well under the
   512 KiB response guard. `histogram.rs` now calls `binning::uniform_bin` for its cell math so both
   tools agree on boundaries.
+- **Tools, not a window** - `ActiveTool::LambdaDelay` / `ActiveTool::AccelEnrich` render like
+  Histogram: setup in the Tool Properties panel (`render_table_tool_properties`), results in the
+  central panel (`render_table_tool_view`). `ActiveTool::generator_kind()` is the one helper the
+  match sites use, and `ActiveTool::ALL` fixes the switcher / View-menu / Cmd+1..5 order, so a new
+  tool is appended there and nowhere else. Tool switches go through `UltraLogApp::set_active_tool`
+  (analytics + table selection reset), not direct assignment.
+- **State is app-level, not per-tab** - unlike `Tab::histogram_state`, `UltraLogApp::table_generator`
+  holds the accumulators, mappings and export options for both generators. The tables are
+  multi-log by design, so the active tab only decides which file *Run / Add current file* reads;
+  switching tabs or tools does not lose a table.
+- **PNG has no text** - the crate has no font rasterizer, so `table_export::render_table_png`
+  draws cells and grid lines only (same as the histogram PNG). `render_table_pdf` draws values,
+  counts and axis labels with built-in Helvetica, whose encoding turns `~` into an arrow, so the
+  confidence markers are `*` (medium) and `?` (low). Both go through `tables::export::cell_value`
+  so PNG, PDF, CSV and clipboard blank the same cells and convert delay units identically.
 - **Auto-suggestion** (`channel_map::suggest_mapping`) - normalization hit (100) → strong name
   hints (50) → spec category + hint (60) → generic hints (40), then a data-plausibility veto on the
   channel median; `overall|avg|average` names lose 10 points so a single sensor beats an averaged

GPS coordinate encodings are auto-detected and normalized to decimal degrees (`GpsCoordSpec` in `src/laps.rs`): NMEA `DDMM.mmmm`, milli/micro/1e-7-scaled integer degrees, and 0-360 longitude.
