Subject: [PATCH] UX improvements (#686)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Introduce "side" mode for system bar, versus classic statusbar on top with launcher bar below
- Automatic system bar mode detection with override by Kconfig/device.properties and secondary override by user via Appereance settings app
- Open a quick-settings menu from the status bar for available Wi-Fi, Bluetooth, GPS, and power controls.
- Apps can display overlays with backdrop or Escape-key dismissal.
- Added focus-container support and improved keyboard navigation, including Fn+Enter on Cardputer devices.
- Power-off controls are available on supported device cards.
- Updated status-bar layouts, simulator display dimensions, and toolbar navigation styling.
- I²C scanning now supports selecting individual buses to rescan.
- SD-card mount status is no longer shown in the status bar.

@@ -6,3 +6,21 @@ Two kernel modules cover LVGL:
 
 - **`lvgl-module`** (`Modules/lvgl-module/`, `<lvgl/*.h>`) owns LVGL's lifecycle: init/deinit, the LVGL task loop, and `lvgl_lock()`/`lvgl_try_lock()`/`lvgl_unlock()` mutex-based locking that any task must hold before touching LVGL objects. It bridges Tactility's device model to LVGL indevs (`lvgl/devices/*.h`: `display`, `pointer`, `keyboard`, `trackball`), and provides shared fonts (`lvgl/fonts.h`: Montserrat text sizes, Material Symbols icon sets for statusbar/launcher/shared use) and a few shared widgets (`lvgl/widgets/*.h`: `toolbar`, `spinner`, `sliderbox`).
 - **`lvgl-window-manager-module`** (`Modules/lvgl-window-manager-module/`, `<lvgl_window_manager/*.h>`) manages a single stacked window per app instance on top of `lvgl-module`. `window_manager_start()`/`window_manager_stop()` create/tear down the root widget (plus optional chrome from a configured `WindowManagerScreenInitFn`); `window_manager_create()`/`window_manager_remove()` push/pop an app's window and (re)populate it via a `WindowCreateWidgetsFn`. Only the topmost window ever has live widgets - burying and resurfacing a window deletes and rebuilds its widget tree rather than hiding/showing it. That rebuild-on-remove path can run `create_widgets` on a *different* app's thread (whichever app's `window_manager_remove()` call caused this window to resurface), so `create_widgets` must only rebuild already-committed state, never decide what happens next - state transitions belong in the app's own `main()` event loop, driven by real `APP_EVENT_RESULT`s.
+
+## Keyboard navigation
+
+- Put groups of related focusable widgets (pills/chips, rows of buttons, toggle tiles) in a grid navigation container with `lvgl_grid_navigation_add()` (`lvgl/grid_navigation.h`). Only the container joins the input group: left/right moves within the group and up/down moves between groups.
+- Never make checkable widgets (switches, checkable buttons) direct input group members: LVGL toggles them on arrow keys. Grid navigation forwards only Enter to them.
+
+## Theming (LSS)
+
+The themes in `Modules/lvgl-module/source/themes/lv_theme_material*.c/.h` are generated: never edit them directly. They're compiled from the LVGL Style Sheets in `Modules/lvgl-module/themes/*.lss` by the LSS tool, a git submodule at `Modules/lvgl-module/lss/` (see its `README.md` for the syntax).
+
+- Styles are defined once and attached to widget types with `apply(<widget>) { <style>: <state/part>; }` rules. Custom widget classes of `lvgl-module` (e.g. `lvgl_card_class`) are declared with `@widget <name>: <class>;`.
+- Change `material.lss` and `material_mono.lss` together, then regenerate (requires `pip install lark`):
+
+```bash
+cd Modules/lvgl-module
+python lss/compile.py themes/material.lss --output source/themes
+python lss/compile.py themes/material_mono.lss --output source/themes
+```
