Please don't do that. It messes with muscle memory. Either have columns always in fixed order or let me customise the order. Google search has dynamic order and while usually Images link is the second one in upper row, sometimes it moves Maps there resulting misclicks. Terrible UX. There are very few cases where dynamic UI makes sense, but IMHO search is not that.
