Consider a Freecell with one new affordance?

@jim, @david — would you consider adding a variant Freecell game in which it is legal to retrieve a card that has gone onto one of the ace-headed stacks? As you can do in Klondike. It's not all that often that such a move would be useful, but in those rare cases it could save a lot of undo-and-redoing.
