- Added --output flag supporting hex, rgb, hsl, rgba, hsla, hexa, and 'all' formats - Implemented HSL/HSLA conversion using internal Python logic - Added --[no-] prefix support for all toggleable flags (json, name, swatch, copy, notify, pick) - Embedded KDE Plasma color picker Python script within the main bash script for portability - Refactored argument parsing to implement a robust priority system (CLI > Desktop Config > Default Config) - Improved validation to catch invalid output formats before triggering the color picker - Updated installation logic to generate all necessary components and sample configuration - Fixed swatch formatting when outputting JSON - Refined desktop mode behavior and configurability
