Appreciation for the Undo function

I would like to express my gratitude to Jim for the comprehensive and useful implementation of the Undo function.

Recently I’ve been fine-tuning the look of my appointment calendar screen which might involve changing the icon and color used for the paid/unpaid flags. When I don’t like that look I just hit undo a couple of times to restore the arrays and text displays to the prior look - which might have taken several change-alls in a Text Display and Procedure changes (several hundred changes). Watching the calendar revert to its prior look step by step amazes me. In the past it wouldn’t have been worth trying different things because of the work to undo it if not satisfactory.
