**Fonts**
Dynamically load text and icon fonts when the device boots.
Font bitdepth depends on whether the device is an ESP32 one and whether it has external RAM available.
When no external RAM is available on ESP32, only small and medium font variants are generated; large font variants refer to the medium size ones.
Implemented Appearance settings app for changing font and font size.
**Other changes**
- Added keyboard shortcuts to delete or rename files in directory views.
- Improved app-grid tile sizing to provide more room for labels.
- Reduced the default LED strip brightness.
- Refactored shell parsing so that the callstack doesn't increase when script complexity increases.
- Improved terminal input handling: input delay from +- 100 ms to at most about 16 ms.
app-module
- Apps now have support for:
- environment variables (inherit from parent app)
- current workdir
- window size (when running in terminal)
- Add type aliases like `AppId` and `PackageId`
- Remove data duplication between ledger and app instance records: create `AppManifestSet`
- `AppManifest` usage safety improved: pass by value where needed, or use `AppId` instead of a manifest.
Terminal and shell
- Moved shell commands into coreutils-module as proper apps.
- Refine stack size for terminal and shell because apps now run with their own task and stack (including in-memory apps)
Platform
- Fix for listing root dir on ESP32: wrap posix directory functions and wire in file systems.
- Moved all platform-specific file system init code to platform subprojects
Other
- Fix for screenshot capture (issue with paths)
- Fixes for coreutils app correctness
- Memory optimizations (use more PSRAM where possible) in various locations such as app-module, shell and terminal.
- `ls` and `help` commands now use terminal width and show columns of data by default
- Created fs helpers at `TactilityKernel/include/tactility/filesystem/fs.h` (partially ported from `ShellFs`)
Features:
- Implemented terminal app based on BreezyBox
- Implemented shell based on BreezyBox
- Added font-module with fixed-width fonts
Improvements:
- Improved application standard-output and error-output routing, including dynamically loaded applications.
- Updated shared icons and Material Symbols mappings.
- Other improvements & fixes
