Includes:

• various UI improvements
  • dark/light theme switchable without restart
  • adjusted styling of some elements/components
• various minor fixes/adjusments
  • probable fix for controls getting stuck sometimes
• added "Clipboard" features
  • copy selected polygons to (literal!) clipboard
    • paste back into FMT or even as text!
  • paste polygons from clipboard into the current FMT
