  • IMP: valign style added to text nodes (txt_add)
  • FIX: Issue where panel shimmers through to desktop
  • FIX: Aircraft switching would crash when enabled
  • FIX: Button click spot now moves with button (when issuing move)
  • FIX: Mouse cursor is now applied when starting scroll wheel grab
  • FIX: hw_adc_input_read would return raw value instead in 0.0-1.0 range
