I’ve found it useful to rename layers, especially when manipulating different portions for selective cutting/engraving. I frequently have a layer named “hold for engraving” which is set to not cut, but to show. For some parts that I’ve cut, there are left and right sides, which don’t get marked as such. By naming the layers, it gives me an easier shot at remembering which ones go where.
Double clicking on the entry brings up the cut settings window with the label as the active field.
I learned something in this test sequence as well. My previous job had named layers and when I activated one of them, the old name appeared. This is a bug, or an undocumented feature, in my opinion.
