## Improvements - Created new base driver classes: `EspLcdDisplayV2' and `EspLcdSpiDisplay` - Updated `St7789Display` to implement `EspLcdSpiDisplay` - Updated all boards with ST7789 display ## Fixes - Ensure that `tmp/` is created on startup (for all writeable filesystems) - Fix for `lv_list` padding on small screen devices - Fix for `PreferencesEsp` not processing result when writing string to NVS ## Other - Remove unused build scripts
