I get used to checkvist moving my items to the right list if I just press 'mm' quickly and write the first couple of letters of a list and press enter. However, the list order/priority isn't static so if I have two lists that start the same, I often get unexpected results since sometimes doing that results the item being moved to the other list I didn't intend the item to go.

So perhaps change the 'move to' list dynamic? Until now, I hadn't noticed that you could undo with ctrl+z too, so I kept going up the page to find the undo message to know whether I can undo the moving. So the undo message perhaps should be always visible for at least a couple of seconds, even when scrolled down?
