>Yesterday I did minor edits to two of my FAQs, and saw them come up to the top of the list, which was not the idea (there was nothing really "new" about the changes). Would it be possible to have an option, to mark edits as minor; or perhaps better the other way round, that an edit (either in FAQs or downloads) must explicitly be marked as a "new version", in order to come to the top of the list?

Yes, should be this way. I think it's currently sorted by the Last Edited date.
