@yukinoh1989 The Operator panel opens when you create a new object. But also when doing certain actions, like move, rotate, etc. As soon as you perform any action on it, the Operator panel disappears, or is replaced by new options, depending on what you do. Also going to edit mode is going to make the panel disappear.
I heard that in the future they want to make it possible to change those settings, even after you edit the object, but I don’t know how certain these plans are.
