Hi Olaf,
Maybe, maybe not. For the backends/scanners where these are marked as advanced, is there another less-advanced way to set the scan area? For example by choosing a paper size like A4 or Letter. If there is, I think I would classify the well-known scan area options as advanced too.
I think, for well-known options application should decide, are they advanced or not. That's why they are well-known.
For other options application can only offer them to user, and it needs a hint, are these options common or advanced.
