good to know - will try it out

The priority is: native dialog if possible (and on iOS, if you are choosing a picture, we treat the photo picker as a native dialog); if not, then use a widget dialog if possible (and if it’s not a QApplication, it’s not possible); if not, then fall back to a plain QML implementation (DefaultFileDialog.qml).

will test this and create example app providing different ways to pick

that's why I'm developing a custom QtQuickControls2 FileBrowser ;-)
(will be available at Github hopefully next week)
