I was just confused when I thought I was editing a layer, but in fact I was dragging around features from identical features in a hidden layer underneath because that hidden layer was selected in the layer legend. I could see the hidden features selected when dragging them, which made me think I was dragging the corresponding visible feature, but then it seemed to snap back when I dropped it, whereas what was happening was that the hidden feature went hidden again. By the time I'd worked out what was happening I'd dragged four or five polygons on my hidden layer all over the place.



I can't think of any good use-case for wanting to edit layers that you have elected to not see. You hide them to get things out of the way, and simplify things. The only thing you should be able to do with a hidden layer is unhide it. I think maybe you shouldn't even be able to click and identify features in it either, which I think you can at the moment...
