 - `scroll_acceleration.enabled` - Enable macOS-style scroll acceleration for smooth, natural scrolling. When enabled, scroll speed increases with rapid scrolling gestures and stays precise for slower movements. **This setting takes precedence over `scroll_speed` and overrides it when enabled.**
 - `scroll_speed` - Controls how fast the TUI scrolls when using scroll commands (minimum: `0.001`, supports decimal values). Defaults to `3`. **Note: This is ignored if `scroll_acceleration.enabled` is set to `true`.**
 - `diff_style` - Controls diff rendering. `"auto"` adapts to terminal width, `"stacked"` always shows a single-column layout.
+- `show_tool_output` - List of tool names whose output is always shown and expanded, even when generic tool output is hidden. Useful for selectively surfacing output from specific tools (e.g. `["bash", "read"]`) while keeping others collapsed.
 
 Use `OPENCODE_TUI_CONFIG` to load a custom TUI config path.
