BTW: if you feel that the gimp should be simplified as possible for beginners, wouldnt be possible to keep advanced features visible for advanced users but not for beginners? but not remove them completelly? single option in preferences (or in gimprc file) which would enable more advanced features which some consider as interface clutter but others may need them?
