I like the Matching exercise for teaching language vocab, and for my students who find it particularly challenging, the more worksheet content I can make quickly for them the better. For them to reinforce vocab, multiple Matching exercises with the same words (but in a different order) would be effective. So ideally I would make one Matching exercise, print it, then simply Shuffle both the left & right columns to quickly produce another one. Unfortunately the Shuffle button as-is only shuffles the right column, and although you can change the order of items in the left column, and it works well, it's a bit cumbersome to drag-and-drop items one-by-one if your goal is to simply randomize the order of all items.
