+- 1. `Settings` - `Interface` - `Theme` - set to `E-Ink` **Pure black and white for better display**
+- 2. `Settings` - `Control` - Turn on `Split Action Bar` **Put the action bar on the side (tablet) / bottom (mobile phone), you can better operate the menu**
+- 3. Enter the article list page - Long press the title bar at the top - Pop up the `Edit Menu` - Move the default disabled `Back`, `Up`, `Down` to the top, save **Tap menu instead swipe gesture**
+- 4. Enter the article detail page - Long press the title bar at the top - Pop up the `Edit Menu` - Move the default disabled `Back`, `Up`, `Down` to the top, save **Tap menu instead swipe gesture**
