Confirmation on Step delete (6.0)

Interesting note on the undo/redo.
I believe I lost a set of my steps earlier after selecting a group of them and then getting "fat fingered" near the Delete key. Problem was I saved and closed the file without realizing I'd done that, so the undo wouldn't have helped then. Guess I'll have to be more careful, but I've always been a fan of delete confirmation. Gives me a chance to second myself
