A great feature is the way LightBurn handles the undo function when using boolean tools. Many times, I will pick the objects in the wrong order and click on the weld or difference tools and it will not be the result I wanted. By pressing CTRL - Z to undo it, LightBurn will then reverse the order of that the objects were selected, and all you have to do is reclick the tool you want to use. Saves from having to try to remember what order you had chosen, and then having to reverse that order. Slick!
That sounds like a great feature… not sure what you are so “grumpy” about. 
You really don’t want to know.
