I need a way to undo my clunky mis-edits. I only see this issue in the Mac threads. It's too easy for me to do an accidental cut or paste editing credit card numbers etc., trying to correct a single digit, for example. I need an undo function. Worse, when I checked, the unwanted change had already been synced to my other device. I had to reconstruct the info from another source. This is a major headache for me. As my eyes and fingers get older, this problem is not going to go away!
