Being able to undo an action is is actually a general usability principle that has been around at least since the 1980s :-).

Fair enough, I should have been clearer. I’m thinking about extending it to CRUD apps for example. I haven’t personally seen any do that, and it might get really involved due to dependencies, integrations, etc.

The Humane Interface, a book on UIs by J. Raskin, talks about the importance of undo/redo.
