- Auto-select widgets in Launcher and apps with toolbars on devices without touch.
- Improved USB HID input reliability, cleanup
- Updated PSRAM settings to improve boot stability on supported devices.
- Prevented duplicate Wi-Fi event subscriptions during screen rebuilds.
- Updated docs
- Fixes in WifiManage and WifiConnect
- Reduced main task stack size
- Moved USB HID stack size to PSRAM when available
- app_manager_find_manifest() now returns a copy instead of a pointer

 ## Higher Priority
 
-- Devices with a keyboard attached should always highlight the first widget (~Cardputer navigation issue), same for LV_INDEV_TYPE_ENCODER being present
+- Move USB host task stacks to SPIRAM when available: esp32_usbhost*.cpp
+- wifi: wifi_add_event_callback() and wifi_remove_event_callback() should be replaced by a subscribe/await pattern like system events.
+  When that's changed reduce LVGL callstack size in Tactility.cpp run()
 - Make it more clear to end-users that an SD card is required to run Tactility
-- Move "# Fix error "PSRAM space not enough for the Flash instructions" on boot:" fix from T-Deck and others to device.py
 - Make it possible to override stack size for an app via config file (loaded at boot), and make it possible to set preferred memory location (e.g. internal/external)
-- Put task stacks in PSRAM when possible.
 - Wrap file operations like fopen/fclose with file_mutex
 - Add bold fonts for e-ink readability improvement
-- Split up Claude instructions: https://code.claude.com/docs/en/memory#import-additional-files
-  and add https://github.com/multica-ai/andrej-karpathy-skills/blob/main/CLAUDE.md
 - Move test projects to their relevant subproject
-- tt_alertdialog start() etc is broken as it can't fetch the app instance id. Fetch automatically via thread context?
-- Migrate Tactility/Paths.cpp functions to TactilityKernel
-- app_manager_find_manifest() should make a copy, not return a pointer.
 - Httpd.cpp: warn if running on same CPU core (or task) as UI/LVGL/window manager.
 - Improve Setup: Show "Step done" screen
 - Improve Setup: Add keyboard/keypad navigation explanation
 - display.h API: get_backlight does not change ref counting, but it should
 - bluetooth: various getters for child devices do not change ref counting, but they should
 - Improve kernel_init.cpp (and other modules): create driver_ensure_added() and driver_ensure_destructed()
-- Remove and migrate `Include/Tactility/kernel/Kernel.h` into `tactility/delay.h`
 - Drivers/audio-codec-module is not a module. Move it somewhere else. Or make it an actual module.
 - LilyGO T-Dongle S3: 1 button control, stop auto-launching web server
 - Core2: support power off via software

 - Get rid of TactilityC in favour of TactilityKernel and kernel modules
 - Improve SPI kernel driver (implement read, write, transactions)
 - Add font design tokens such as "regular", "title" and "smaller". Perhaps via the LVGL kernel module.
-- Kernel concepts for ELF loading (generic approach for GUI apps, console apps, libraries).
 - Fix glitches when installing app via App Hub with 4.3" Waveshare
 - TCA9534 keyboards should use interrupts
 - External app loading: Check the version of Tactility and check ESP target hardware to check for compatibility

 ## Medium Priority
 
+- `platform-esp32`'s module drivers are declared in start/stop of the module but they should be set via `Module::drivers`
+- `struct Driver` has an `.owner`, but it's not always set. Either validate on Module construct that it matches, or otherwise set it during module start. The problem: NULL parent currently means that driver is not removable. This clashes with setting it dynamically. Consider some kind of flag to determine removability.
 - Consider moving certain drivers into separate modules: audio, bt, wifi, etc
 - Consider using https://github.com/Graphify-Labs/graphify
 - Consider implementing LVGL gridnav in apps https://lvgl.io/docs/open/9.3/details/auxiliary-modules/gridnav.html
-- Implement a LED kernel driver (single colour and RGB, plain GPIO and PWM)
 - Make USB host driver disabled by default, so it doesn't consume memory
 - Filtering for apps in App Hub:
   - apps that only work on a specific device
 - Diceware app has large "+" and "-' buttons on Cardputer. It should be smaller.
-- Create PwmRgbLedDevice class and implement it for all CYD devices
 - TactilityTool: Make API compatibility table (and check for compatibility in the tool itself)
 - Improve EspLcdDisplay to contain all the standard configuration options, and implement a default init function. Add a configuration class.
-- Make WiFi setup app that starts an access point and hosts a webpage to set up the device.
-  This will be useful for devices without a screen, a small screen or a non-touch screen.
 - Unify the way displays are dimmed. Some implementations turn off the display when it's fully dimmed. Make this a separate functionality.
 - Bug: Crash handling app cannot be exited with an EncoderDevice. (current work-around is to manually reset the device)

 - Calculator app should show regular text input field on non-touch devices that have a keyboard (Cardputer, T-Lora Pager)
 - Allow for WSAD keys to navigate LVGL (this is extra nice for cardputer, but just handy in general)
 - Create a "How to" app for a device. It could explain things like keyboard navigation on first start.
