Question: In the Settings/Print/Export popups, It would be nice to have the header text(s) of all the parent AdvancedDataGridColumnGroup headers appended with the actual column header text.

Answer: These popups are in the client section of the code, i.e. you can fully control their appearance. Attached, please find a modified SettingsPopup.mxml that uses a custom labelFunction to append the column group if there is one.
