+The main GUI has a **Configurations avancées** button that opens a dedicated
+editor for:
+- `ARK_Main_Config.yml`
+- `bcasl.yml`
+- `.ark/pref.json` (workspace‑specific preferences)

+Features (lightweight by design):
+- Monospace editor
+- Simple YAML/JSON syntax highlighting
+- Diff view before saving
+- Basic validation on save (YAML/JSON)
+
+## Workspace Prefs (.ark/pref.json)
+
+Per‑workspace preferences are stored in:
+```
+<workspace>/.ark/pref.json

+Currently used keys:
+```json

+  "venv_path": "/abs/path/to/venv" | null
+}
+```

+These values are updated when you select a venv or System Python, and are
+re‑applied automatically when the workspace is loaded.

+- The SDK also accepts the plugin folder name as ID (case‑insensitive).
+- If a key is missing, `translate()` falls back to the default you pass in.

 **Sandbox, Timeout, Parallelism**
 - If `options.sandbox` is `true`, plugins can run in isolated processes.
 - Timeout via `options.plugin_timeout_s` or `PYCOMPILER_BCASL_PLUGIN_TIMEOUT`.
