When using the AI, it would be great to have an undo button. Originally, you could ask the AI to undo what it had just added, but that capability seems to have disappeared. Also, the AI will say it will add to a box; however, it replaces it, and you lose the information that was there originally. With no undo, there is no way to get it back. Is it possible for it to distinguish between adding and replacing, so we don't always have to work in empty boxes?
