Cocoa: ColorDialog can have options?
LCL: implement TColorDialog.Options. Currently only supported for Win32/Win64 widgetset. Issue #22717. The default value differs from Delphi (7) for backwards compatibility (CC_FULLOPEN flag was always set in Windows).
this is text of new Lazarus patch.
AFAIR macOS dialog also can be collapsed/extended. I saw it in older macOS. if so, is it possible to implement TColorDialog.Options for macOS?
