Use case: grocery list. Walking through the supermarket I tick of the stuff I got in my basket. Currently they stay in my list and they are only moved to the bottom when I shake my device.
However shaking the device also resets the sort order, which for me is rather unwanted since I sort the stuff in the order they are stacked in the shop. In other words: in the shop I first pass the bread department, so I have bread at the top of the list and so on.
I would like to be able to specify a "drop to bottom when finished" option for each of the lists. This should keep my precious sort order the way it is.
