- Created `tactility-headless` to support ESP32 firmwares that don't require graphics
- `tactility` subproject now contains both PC and ESP32 code (to avoid having to split up `tactility` and `tactility-headless` into separate projects, which would result in a very complex dependency tree)
- `tactility` subproject is now defined as component for ESP32 and as regular module for PC
- Improvements for dispatcher
- Added `project-structure.puml` to docs
- `Gui` service now depends on `Loader` service instead of the reverse
- Added `statusbar_updater` service for updating Wi-Fi and SD card icons
- Add dispatcher mechanism (a queue for function calls) and tests
- Added tests for MessageQueue
- Fix FreeRTOS config for simulator
- Explicit dependencies for touch-related libs, because minor version changes caused broken builds on CI.
- Specify IDF SDK version in a safer way
- Fix for crash when polling SD card presence (Need to implement a universal locking mechanism later on)
- Updated `ideas.md`
- SD card task prio set to low
- Implemented GPIO app
- LVGL now allocates freely (as opposed to using a fixed-size buffer): when it goes OOM, it just deletes image cache and starts behaving erratically.
- Created Files app to browse PC and ESP32 files.
- Refactored toolbars so it's now a proper widget and allows for changing its properties from the app
- Toolbar now has extra action buttons
- Settings app now has a proper icon
- Minor cleanup in Desktop app
